HDB3（High Density Binary－3）码是AMI码的一种改进型。HDB3码保持了AMI码的优点，克服了AMI码在遇到连“0”长时难以提取定时信息的困难，因而获得广泛应用。CCITT已建议把HDB3码作为PCM终端设备一次群到三次群的接口码型。我本次毕业设计的主要内容就是基于Verilog HDL语言的HDB3编码器的设计，它所要达到的要求就是能从软件方面来实现HDB3编码器的基本功能，并能协调整个设计，使之达到预想的要求。设计的核心部分是：在Quartus Ⅱ的软件平台上，用 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报

Rayleigh fading channel是一种无线电信号传播环境的统计模型。这种模型假设信号通过无线信道之后，其信号幅度是随机的“衰落”，并且其包络服从瑞利分布。

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). You should run "Simulation.m" function that include all modules.
