This packet is a IS-95 baseband simulation for 1 data channel of 9.6 KBps rate. The simulation is written for static channel and AWGN noise. The packet include: 1) Packet Builder (Viterbi Encoding, Interleaver, PN generation) 2) Modulator (RRC filter) 3) Demodulator (Matched Filter, RAKE receiver) 4) Receiver (HD or SD) (Deinterleaver, Viterbi Decoder).

This package provides a complete http client library. It currently implements most of the relevant parts of the HTTP/1.0 and HTTP/1.1 protocols, including the request methods HEAD, GET, POST and PUT, and automatic handling of authorization, redirection requests, and cookies. Furthermore the included Codecs class contains coders and decoders for the base64, quoted-printable, URL-encoding, chunked and the multipart/form-data encodings. The whole thing is free, and licenced under the GNU Lesser General Public License (LGPL) (note that this is not the same as the GPL).

Peers is a very minimalistic SIP User-Agent. It s a softphone, written in java, and it has been tested on linux and windows. It allows a user to call from one PC to another on a local area network, using SIP/SDP/RTP with Ulaw encoding for voice.

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。

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.

主題 : Low power Modified Booth Multiplier 介紹 : 為了節省乘法器面積、加快速度等等，許多文獻根據乘法器中架構提出改進的方式，而其中在1951年，A. D. Booth教授提出了一種名為radix-2 Booth演算法，演算法原理是在LSB前一個位元補上“0”，再由LSB至MSB以每兩個位元為一個Group，而下一個Group的LSB會與上一個Group的MSB重疊(overlap)，Group中的位元。 Booth編碼表進行編碼(Booth Encoding)後再產生部分乘積進而得到最後的結果。 Radix-2 Booth演算法在1961年由O. L. Macsorley教授改良後，提出了radix-4 Booth演算法(modified Booth algorithm)，此演算法的差異為Group所涵括的位元由原先的2個位元變為3個位元。
