这是一篇讲通信理论的文章，非常经典，可以作为课外学习使用 (This is an article tackling with communication theory, very classic, can be used as extra-curricular learning)

PMA规约模拟测试软件。适合初学者使用，包含几个常用规约(PMA Statute of the simulation test software)

（1）请推导出单径瑞利信道中的BPSK相干解调的理论误码率性能，并画出比特信噪比与误码率的关系曲线。 （2）在单径瑞利信道中，请设计一种时分的导引辅助的信道估计方法，用Simulink进行仿真，测量BPSK的误码率性能，画出比特信噪比与误码率的关系曲线，并与(1)的曲线进行对比。 ((1) derived from single-Path Rayleigh channel coherent demodulation of BPSK theoretical bit error rate performance and draw-bit signal to noise ratio and bit error rate curve. (2) in a single Path Rayleigh channel, please design a guided night-assisted channel estimation methods, using Simulink simulation, surveying BPSK BER performance, drawn-bit signal to noise ratio and bit error rate curve, and with (1) comparing the curve.)

程序使用了自相关性和互相关性较好的gold码作为扩频序列，直扩，扩频增益设置为31，模拟用户数为4(Program uses a self-correlation and cross-correlation of the better gold code as spreading sequence, direct expansion, spreading gain is set to 31 to simulate the number of users of 4)

基于阵列信号处理的跳频信号盲检测和参数盲估计matlab 仿真(Matlab simulation of blind detection of frequency hopping signal based on array signal processing)

GPRS is a communication technology that allows data acquisition systems to overcome the difficulty of cabling for wide area remote sites. GPRS applications are becoming more and more prevalent due to the ease with which they can be implemented, but the dynamic IP address issues associated with GPRS networking continue to frustrate system integrators.
