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 ...

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）。从终端读入电文，写到tobetrans文件中，统计电文的字符集合和对应的权值集合，建立哈夫曼树，并将哈夫曼树存于文件hfmtree中。
（2）C：编码（Coding ）。利用已建好的哈夫曼树（如不在内存，则从文件hfmtree中读入），对文件tobetrans中的正文进行编码，然后将结果存入文件codefile中。

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 ...
