设载波频率为20Hz，信息速率为2Baud,用MatLab画出QPSK信号波形。-Carrier frequency set to 20Hz, the information rate of 2Baud, using MatLab draw QPSK signal waveform.

是现在通信编译码中turbo码的源程序，是用MAP算法实现！～-is now communications Encoding turbo code of the source, is to use MAP algorithm! ~

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.
