在GSM通信系统中，Viterbi检测是一个及其重要的部分，许多的研究人员在这里花费了大量的心血。参考各种资料，我们总结得出以下Viterbi软输出算法，与传统的硬判决方法相比，可以提高2～3个db的增益：-In GSM communication systems, Viterbi detection is an important part of many researchers here spent a lot of effort. Reference to a variety of information, we summarize the following soft-output Viterbi algorithm, with the traditional hard-decision method, can be raised by 2 ~ 3 db gain:

实现禁位自动排列在禁位中具体实现了此方法所以这是一个创新很有应用价值在VC平台上调试通过-achieve automatic cut---arranged in a specific ban on the method to achieve this is a very innovative application value in the VC through debugging platform

这个也是关于空间谱的matlab 挺好的 可以

本源码是一个bbs客户端程序，能够根据bbs的协议原则，对每个字节进行分析，同时也能够同时显示中文和英文！-the source is a bulletin board clients, according to the agreement in principle with each other, for each byte analysis, but also can display Chinese and English!

一个非常全面的关于串口通讯方面的饭卡系统程序源码，大家共享-A very comprehensive on the serial communication system procedures饭卡source, everyone shared

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.

加性高斯白噪声 AWGN(Additive White Gaussian Noise) 是最基本的噪声与干扰模型。加性噪声：叠加在信号上的一种噪声，通常记为n(t)，而且无论有无信号，噪声n(t)都是始终存在的。因此通常称它为加性噪声或者加性干扰。

为调试设备编写的RS232转以太网通信软件。 均使用异步通信方式，RS232使用API编写，以太网使用Sockte类。程序中使用了两个独立线程，线程间以消息方式传递数据，本程序中包括：RS232异步通信、Sockte异步通信、用户界面线程、线程间通信。-Equipment prepared for debugging RS232 to Ethernet communications software. Only use asynchronous communication mode, RS232 using the API written in Ethernet using Sockte class. The program uses two separate threads, the threads in the message is transmitted data, this program includes: RS232 asynchronous communication, Sockte asynchronous communication, the user interface thread, communication between threads.
