EDGE(Enhanced Data Rate for GSM Evolution)

EDGE is Enhanced Data Rate for GSM Evolution acronym, that is Enhanced Data Rates for GSM Evolution. EDGE is a transition from GSM to 3G technology, it is mainly used in the GSM system, a new modulation method, that is the most advanced multi-slot operation and 8PSK modulation. Because 8PSK can be used in the existing GSM network GMSK modulation symbols carrying information space extended from 1 to 3, so that the information contained in each symbol is 3 times the original. There the same name gladiator Edge.Brief Description ofThe reason that EDGE to GPRS to the third generation mobile communication technology transition program (GPRS commonly known as 2.5G, EDGE commonly known as 2.75G., 3G Needless to say it), mainly because the technology to fully utilize the existing GSM resources. Because in addition to the use of existing GSM frequency, and also use most of the existing GSM equipment, but only on the network software and hardware to do some minor modifications, it enables operators to provide mobile users such as Internet browsing , video teleconferencing and high-speed wireless multimedia services such as e-mail transmission, that is the third generation mobile network in advance of the commercialization of multimedia communications for the user to provide personal services. Because EDGE is a range of existing second-generation mobile networks and third-generation mobile networks the transition between the technology, than the "second half" GPRS technology is more excellent, so some people call it "2.75 generation" technology. EDGE can also coexist with the future of the WCDMA standard, which is the flexibility it has advantages. EDGE technology mainly affect the existing GSM network wireless access part of the Base Transceiver Station (BTS) and base station controller in GSM (BSC), and based on circuit switching and packet switching applications and interfaces, and not much impact. Therefore, network operators can maximize the use of existing wireless network equipment, only a small amount of the investment can be deployed EDGE, and through the mobile switching center (MSC) and Serving GPRS Support Node (SGSN) can also be used to retain the existing network interface. In fact, EDGE GSM applications to improve these existing performance and efficiency and for the future of broadband services possible. EDGE GPRS technology to effectively improve the efficiency of channel coding and high-speed mobile data standard, it's up to the maximum rate of 384kbit / s, to some extent, saving network investment, can fully meet future bandwidth requirements of wireless multimedia applications. In the long run, it will gradually replace the GPRS as the third generation mobile communication systems with the closest a technology.Technology to locateGSM and TDMA/136 is now the world's second-generation common cellular standards. There are currently more than 100 countries, 100 million people use GSM, there are nearly 100 countries, about 95 million users use TDMA/136 system family (including ELA-553 and IS-54) service. As between the existing second-generation mobile communication systems and third-generation mobile communication systems as a transitional data communications technology, EDGE (EnhancedDatarate for GSM Evolution) technology to dramatically improve the existing GSM network data service rate. But to give full play to advantages of speed of EDGE, operators must be on the existing GSM system architecture and all the equipment to be modified.EDGE technology is different from the GSM has the advantage of: (1). 8PSK modulation (2). Enhanced AMR encoding (3). MCS1 ~ 9 nine kinds of channel modulation coding (4). Link Adaptation (LA ) (5) incremental redundancy transmission (IR) (6). RLC window size is adjusted automatically.

Gears

Gears, formerly known as Google Gears, is a software developed by Google, allows users offline access, but is still in beta stage. The software side through the local SQLite database so the information can scratch up. So the page is achieved through the buffer, not made from the actual network. Moreover, Web-related programs through the Gears will be periodic temporary local data and information on the network to do synchronization. If the network is temporarily unavailable, the synchronization process will be delayed until the network is restored. So, Gears of Web-related applications are not immediate. Gears is a free and open source software to BSD license.IntroductionGoogle Gears browser extension by the way to add the JavaScript API allows script to access the browser's cache local database. This extension only supports Firefox and Internet Explorer and the need to work on Windows, Mac OS X or Linux. [2] currently have a browser that supports the development version of Safari. At present, Google Reader, Google documents, Google Mail, Google Calendar and Google Chrome is Google all of the five programs that use Google Gears, but there are other Web applications, such as Remember the Milk has added Google Gears this feature. In Google Reader, the online mode and offline mode need to artificially switch, mainly because the data transmission process differ. In other applications, such as Remember the Milk, online and offline mode seamlessly switch.Google Gears is a web application used to develop off-line tools, is a JavaScript application programming interface, through a variety of Google Gears allows Web applications to run offline, allowing users on-line or Web applications to run offline , its source code is open.
Google Gears and Microsoft, the biggest difference between similar products is that it can run in the offline case, you can start from the user's computer hard drive, create the file can be stored on the hard drive can also read files from the hard disk.
 Now with Google Gears, Google's software of Google Reader, a news browser, has been able to off-line browsing. When connected to the network, users can also update the subscription content. There will be a succession of other software applications Google Gears technology.Google CEO Eric Schmidt foreign claims: "Google Gears to solve the biggest limitations of the browser, making the browser a variety of applications can be equipped with a powerful platform."
 Google said Google Gears can be used in a variety of popular operating systems on a variety of mainstream browsers, its operating system including Windows, Mac and Linux, browsers include Firefox and Opera. But Google did not mention Microsoft's browser, IE.The Google released Google Gears, Microsoft is probably the most worried about Google's open source initiatives of. Google wants to promote the industry through Google Gears to form a unified standard to compete with Microsoft.
 According to Gartner analyst David Smith said that Microsoft would be forced either to support Google's open-source project, or will take similar initiatives.
Gears has now begun to support IE6 browser above.Currently, the valley has been reported in Austria to give up Google Gears, and the use of the HTML5 standard to replace its original function. In Google recently updated Google Docs update on the blog, also revealed that the final implementation of the HTML5 Time: May 3, 2010. The reason, in addition to maintaining the simplicity of the browser, another noteworthy issue is the compatibility of Google Gears.
Gears with HTML5 instead of the obvious: the next generation network HTML, HTML5 is a network standard, rather than the plug-in. Gears not only to achieve the function, and no longer have to worry about compatibility issues. For Google, you need not worry about step Adobe's footsteps, Docs, as is Apple shut out as Flash.

Digital Camera Noise

Digital camera noise mainly refers to the CCD ( CMOS ) will be light as a received signal receiving and output generated in the process of image of the rough part, also refers to the image of the external pixel, usually by the electronic interference. Looks like the image blurred, with some small rough point. We usually take digital photos if you use personal computer will shoot to high definition image shrinking later see, may not pay attention to. However, if the original image, then there will be no color ( false color), the color image noise is false.

Definition

In addition to noise, another is as easy to confuse this noise, is dead. In a digital camera the same setting conditions, if images of miscellaneous points always appear in the same location, that this digital camera being dead, the dead pixel manufacturers generally have more, if the pixel number exceeds a specified amount, to distributors and manufacturers to replace the camera. If the noise does not appear in the same location, then these miscellaneous point is formed when the noise due to the use of.

Noise: CCD and CMOS photosensitive element have thermal stability ( hot pixel ) problem, is the imaging quality and temperature, if the camera 's temperature increases, the noise signal is strong, will be on the screen should not have a place to form colored spots, the point is we are speaking of the noise. Various brands of various types of camera on noise control are not the same, the same type of fear cameras also have certain individual differences, but also some cameras have noise reduction function. But the pixel is now all DC failed to completely overcome the problem ( high sensitivity ( ISO ), especially for long time exposure, or the camera when the temperature rises ).

Reason

CCD and CMOS photosensitive element have thermal stability ( hot pixel ) problem, is the imaging quality and temperature of the machine, if the temperature increases, the noise signal is strong, will be on the screen should not have a place to form colored spots, the point is we are speaking of the noise. Various brands of various types of camera on noise control are not the same, the same camera models also have individual differences, but also some cameras have noise reduction function. But the noise problem is now all DC failed to completely overcome the problem ( high sensitivity ( ISO ), especially for long time exposure, or the camera when the temperature rises ). Noise and sensor structure and the number of processor differences and different.

Long time exposure generated noise

This kind of phenomenon is most seen in the use of low ISO shooting night, in the darkness of the image of the night sky, there are some random spot. Can noise and ISO coefficient relationship

Say the reason why is because the processor cannot deal with a slow shutter speed brings tremendous workload, leading some specific pixel caused by the loss of control. In order to prevent the generation of such image noise, some digital camera with a known as" noise " function.

If the use of noise reduction function, the recorded image will use digital processing method to eliminate image noise, therefore in the save completed before the need to spend a little extra time. But with noise reduction function of the opening, the picture detail loss.
