This a software runing on the matlab, it is used in the channel coding simulation.
It include DVB-S2 LDPC, Covolution turbo, and block turbo code, You can choose which channel coding to run.
it run the encoder and add white noise in the channel, then it run the decoder, and compute the error rate.
This book is intended for "hands-on" developers or advanced students interested in understanding the strategies and tactics of concurrent network programming using C++ and object-oriented design. We describe the key design dimensions, patterns, and principles needed to develop flexible and efficient concurrent networked applications quickly and easily. Our numerous C++ code examples reinforce the design concepts and illustrate concretely how to use the core classes in ACE right away. We also take you "behind the scenes" to understand how and why the IPC and concurrency mechanisms in the ACE toolkit are designed the way they are. This material will help to enhance your design skills and to apply C++ and patterns more effectively in your own object-oriented networked applications.
USB海量存儲設(shè)備類規(guī)范包括四個(gè)獨(dú)立的子類規(guī)范：(ATA command的那個(gè)沒有)
①USB Mass Storgage Class Control/Bulk/Interrupt(CBI)Transport
②USB Mass Storage Class Bulk-Only Transport
③USB Mass Storage Class ATA Command Block
④USB Mass Stroage Class UFI Command Specification。
前兩個(gè)子規(guī)范定義了數(shù)據(jù)/命令/狀態(tài)在USB上的傳輸方法。
Bulk-Only傳輸規(guī)范僅僅使用Bulk端點(diǎn)傳送數(shù)據(jù)/命令/狀態(tài)，
CBI傳輸規(guī)范則使用Control/Bulk/Interrupt三種類型的端點(diǎn)進(jìn)行數(shù)據(jù)/命令/狀態(tài)傳送。
后兩個(gè)子規(guī)范定義了對存儲介質(zhì)的操作命令。
ATA 命令規(guī)范用于硬盤。
UFI命令規(guī)范是針對USB移動存儲而制定的，實(shí)際上UFI命令格式是基于SFF-8070i和SCSI-2規(guī)范，總共定義了19個(gè)12字節(jié)長度的操作命令。
<Spring in action>原版和代碼,是學(xué)習(xí)Spring的好資料,本書分為三大部分和兩個(gè)附錄，每一部分專注于Spring框架的一個(gè)領(lǐng)域：核心層、中間層和Web層。第一部分展示了Spring框架的兩個(gè)核心概念：反向控制（Inversion of Control，IoC）和面向切面編程（Aspect-Oriented Programming，AOP），以便理解Spring的基礎(chǔ)原理，這些基礎(chǔ)原理在本書各個(gè)章節(jié)都會用到。第二部分在第1章介紹的IoC和AOP基礎(chǔ)之上，展示了如何將這兩個(gè)概念應(yīng)用到應(yīng)用系統(tǒng)的中間層。第三部分走出中間層邁向顯示層，在很多J2EE系統(tǒng)中顯示層被稱為Web層。附錄A介紹如何開始自己的Spring應(yīng)用系統(tǒng)，如何下載Spring以及如何編寫Ant配置文件。本書的每一部分既是建立在前一部分的基礎(chǔ)上，同時(shí)也都是獨(dú)立存在的，所以，讀者不必從頭開始就可以深入到各個(gè)主題。
With a worldwide community of users and more than a million dedicated programmers, Perl has proven to be the most effective language for the latest trends in computing and business.
Every programmer must keep up with the latest tools and techniques. This updated version of Advanced Perl Programming from O Reilly gives you the essential knowledge of the modern Perl programmer. Whatever your current level of Perl expertise, this book will help you push your skills to the next level and become a more accomplished programmer.
O Reilly s most high-level Perl tutorial to date, Advanced Perl Programming, Second Edition teaches you all the complex techniques for production-ready Perl programs. This completely updated guide clearly explains concepts such as introspection, overriding built-ins, extending Perl s object-oriented model, and testing your code for greater stability.

State machine design techniques for Verilog and VHDL
Abstract : Designing a synchronous finite state Another way of organizing a state machine (FSM) is a common task for a digital logic only one logic block as shown in
engineer. This paper will discuss a variety of issues regarding FSM design using Synopsys Design Compiler . Verilog and VHDL coding styles will be 2.0 Basic HDL coding
presented. Different methodologies will be compared using real-world examples.
