1）I：初始化（Initialization）。從終端讀入電文，寫到tobetrans文件中，統計電文的字符集合和對應的權值集合，建立哈夫曼樹，并將哈夫曼樹存于文件hfmtree中。 （2）C：編碼（Coding ）。利用已建好的哈夫曼樹（如不在內存，則從文件hfmtree中讀入），對文件tobetrans中的正文進行編碼，然后將結果存入文件codefile中。 （3）D：譯碼（Decoding）。利用已建好的哈夫曼樹將文件codefile中的代碼進行譯碼，結果存入文件textfile中。 （4）P：印代碼文件（Print）。將文件codefile以緊湊格式顯示在終端上，每行50個代碼。同時將此字符形式的編碼文件寫入文件codeprint中。 （5）T：印哈夫曼樹（Tree printing）。將已在內存中的哈夫曼樹以直觀的方式（樹或凹入表形式）顯示在終端上，同時將此字符形式的哈夫曼樹寫入文件treeprint中。 用戶界面要求設計為“菜單”方式。 修改你的系統，實現對你的系統的源程序的編碼和譯碼（主要是將行尾符編/譯碼問題）。實現各個轉換操作的源/目標文件，均由用戶在選擇此操作時指定。

The main file in this list of programs is "vblast.m". Type "help vblast" on the command line for details.Study the coding by stepping through the program. These programs require around 5000 packets for reasonable plotting accuracy.This has been implemented for a 2x2 system. The reader can program other variations. The program has been tested on MATLAB version 6.0 and above with signal processing toolbox and communication toolbox options.

This chapter contains sample programs for determining capacity. The reader is advised to go through the coding. The file "capacity_water.m" is for measuring the waterfilling capacity. It should be made to work with a file similar to "capacity_plot_main.m". The latter file deals with all the other capacity plots given in the book in Chapter 2. All programs are verified with MATLAB versions 6.0 and above with signal processing and communications toolboxes.

This a very simple baseband simulator for SC-FDMA system. This simulator is part of the upcoming book “Single Carrier FDMA: A New Air Interface for Long Term Evolution” (Wiley, Nov. 2008) which I co-authored with professor David J. Goodman at Polytechnic University. The purpose of this simulator is to give some concrete idea of how SC-FDMA system works. It does lack many realistic and sophisticated features such as channel coding, time-varying fading channel model, soft decision decoding, etc. Regardless, I am hoping that it will help you understand SC-FDMA which is a fairly new development in 3GPP LTE.

With the advent of multimedia, digital signal processing (DSP) of sound has emerged from the shadow of bandwidth-limited speech processing. Today, the main appli- cations of audio DSP are high quality audio coding and the digital generation and manipulation of music signals. They share common research topics including percep- tual measurement techniques and analysis/synthesis methods. Smaller but nonetheless very important topics are hearing aids using signal processing technology and hardware architectures for digital signal processing of audio. In all these areas the last decade has seen a significant amount of application oriented research.

Modern C++ Design is an important book. Fundamentally, it demonstrates generic patterns or pattern templates as a powerful new way of creating extensible designs in C++--a new way to combine templates and patterns that you may never have dreamt was possible, but is. If your work involves C++ design and coding, you should read this book. Highly recommended.-Herb Sutter。好書！

MATLAB Code for Optimal Quincunx Filter Bank Design Yi Chen July 17, 2006 This file introduces the MATLAB code that implements the two algorithms (i.e., Algorithms 1 and 2 in [1], or Algorithms 4.1 and 4.2 in [2]) used for the construction of quincunx filter banks with perfect reconstruction, linear phase, high coding gain, certain vanishing moments properties, and good frequency selectivity. The code can be used to design quincunx filter banks with two, three, or four lifting steps. The SeDuMi Matlab toolbox [3] is used to solve the second-order cone programming subproblems in the two algorithms, and must be installed in order for this code to work.
