JAVA下的TCP/IP同步并发通信框架

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.

这是本人大三时自己编的通信信号的PCM编码系统程序，文件里有编码，解码程序，可以计算量化误差，计算信噪比等，很实用， 希望分享给大家，对学习通信的孩子们有用

正交频分复用（OFDM）系统是一种多载波系统，其利用并行处理技术允许在许多的同时传输数据的密切隔开，正交子载波。快速傅立叶逆变换（IFFT）和快速傅立叶变换（FFT）在传统的OFDM系统被用于复用信号一起和解码信号在分别的接收机。本文研究的性能离散傅立叶变换正交基频分复用（DFT-OFDM）。
