Abstract-The effect of the companding process on QAM signals has been under investigation for the past several years. The compander, included in the PCM telephone network to improve voice performance, has an unusual affect on digital QAM data signals which are transmitted Over the same channel. The quantization noise, generated by the companding process which is multiplicative (and asymmetric), degrades the detectability performance of the outermost points of the QAM constellation more than that of the inner points. The combined effect of the companding noise and the inherent white gaussian noise of the system, leads us to a re-examination of signal constellation design. In this paper we investigate the detectability performance of a number of candidates for signal constellations including, a typical rectangular QAM constellation, the same constellation with the addition of a smear-desmear operation, and two new improved QAM constellation designs with two-dimensional warpi

Application (fix point) for playing MP3 data on embedded systems. mp3play is designed to be able to play mp3 data files within the local filesystem (which can be a network filesystem), or fetch files to play via http Over a network. For the http case the address can specify a streaming MP3 server.

Atmel’s AT91SAM7FP105 is a low pincount FingerChip processor based on the 32-bit ARM RISC processor. It features a on-chip biometric engine performing enrollment verification and identification, an internal record cache of up to 25 records and a secure command protocol Over USB, SPI, UART. This protocol enables an external host system or processor to control the onchip bioengine functions, manipulate the record cache, and securely export record cache records for external storage. Together with the FingerChip sensor device AT77C104B, it forms an embedded, secured biometric turnkey solution.

xl2tpd is an implementation of the Layer 2 Tunnelling Protocol (RFC 2661). L2TP allows you to tunnel PPP Over UDP. Some ISPs use L2TP to tunnel user sessions from dial-in servers (modem banks, ADSL DSLAMs) to back-end PPP servers. Another important application is Virtual Private Networks where the IPsec protocol is used to secure the L2TP connection (L2TP/IPsec, RFC 3193). The L2TP/IPsec protocol is mainly used by Windows and Mac OS X clients. On Linux, xl2tpd can be used in combination with IPsec implementations such as Openswan.

The kernel-ica package is a Matlab program that implements the Kernel ICA algorithm for independent component analysis (ICA). The Kernel ICA algorithm is based on the minimization of a contrast function based on kernel ideas. A contrast function measures the statistical dependence between components, thus when applied to estimated components and minimized Over possible demixing matrices, components that are as independent as possible are found.

一种比较好的抗锯齿算法 Add myaa.m to your path and enjoy anti-aliased professionally looking graphics in Matlab at any time. Myaa works with any kind of graphic (3-D, plots, scatterplots, ...) and even adds anti-aliasing to text, ui controls and grids. Myaa is ideal for complex, cluttered and saturated plots. See attached screenshot for a demonstration. More examples included in the code, just run help myaa . Curiosa: For those of you who publish your code often, an undocumented anti-aliasing option is included in the snapnow.m function in Matlab. To publish a file called test.m you can do: opts.figureSnapMethod = antialiased publish( test.m ,opts) However, you will have more control Over the process using myaa, which is also the best choice when using Matlab interactively.

This book is for you if You re no "dummy," and you need to get quickly up to speed in intermediate to advanced C++ You ve had some experience in C++ programming, but reading intermediate and advanced C++ books is slow-going You ve had an introductory C++ course, but you ve found that you still can t follow your colleagues when they re describing their C++ designs and code You re an experienced C or Java programmer, but you don t yet have the experience to develop nuanced C++ code and designs You re a C++ expert, and you re looking for an alternative to answering the same questions from your less-experienced colleagues Over and Over again C++ Common Knowledge cOvers essential but commonly misunderstood topics in C++ programming and design while filtering out needless complexity in the discussion of each topic. What remains is a clear distillation of the essentials required for production C++ programming, presented in the author s trademark incisive, engaging style.

精致、漂亮、实用的日历选择代码，Calendar is a Javascript class that adds accessible and unobtrusive date-pickers to your form elements. This class is a compilation of many date-pickers I have implemented Over the years and has been completely re-written for Mootools. I have tried to include all the features that have been most useful while streamlining the class itself to keep it as small as possible. Use the links below to see what features are available in Calendar and how it might enhance the accessibility, usability and validation of form elements on your website.

This GUI can be used by entering nu at the MATLAB command prompt. The user can either select a function (f(x)) of their choice or a statistical distribution probability distribution function to plot Over a user defined range. The function s integral can be evaluated Over a user defined range by using: The composite trapezium, simpsons and gauss-legendre rules. This is useful for calculating accurate probabilities that one might see in statistical tables.
