说明：  仿真对数正态阴影衰落和仿真了一个BPSK通信系统，并与AWGN信道下的理论误码率结果进行了比较(Log-normal Shadowing PL model;Simulate a BPSK communication system, comparing simulated with theoretical BER results under AWGN channel)

可生成rom.初学者可以看看。很不错的。理解后生成rom很容易的。(LPM_ROM .It is good for VHDL new learner)

64QAM using CMA algorithm

4FSK调制解调的matlab代码。采用相干解调的方式4FSK进行解调，与大多数方案的包络检波不同。基带信号用四种电平来表示，与调制信号相区分。(Demodulation matlab code 4FSK modulation. Coherent demodulation 4FSK demodulates Unlike most programs envelope detector,. The baseband signal is represented with four level distinguish phase with the modulation signal.)

This paper presents a performance of the UWB system in a time hopping binary pulse position ultra-wideband modulation scheme (TH BPPM-UWB) in the presence of an AWGN channel.

说明：  ldpc编码，里面有ldpc编码，译码以及一系列的具体说明(ldpc encode,ldpc decode and so on)

说明：  雷达发射宽带信号，线性调频信号模糊度函数(Radar transmitting wideband signal, ambiguity function of LFM signal)
