通过调用计算雷达的信噪比，对比雷达在三咱不同雷达截面积下的信噪比，从而分析不同雷达截面积下信噪比情况是如何的，得出相应结论(Calculated by calling the radar signal-to-noise ratio than radar signal-to-noise ratio in the three Zan different radar cross section, which is how to analyze the signal-to-noise ratio in a different radar cross section, draw the corresponding conclusions)

这是一个将语音信号通过DPCM编码传输的仿真测试程序，内有详细注释，希望对大家有用。(This is a voice signal transmission through the DPCM code simulation testing procedures, with detailed notes, We hope that the right useful.)

光纤放大器模拟程序，包括泵浦功率、光纤增益、光纤长度等参数(fiber amplifier)

Optimal Resource Allocation and EE-SE Trade-Off in Hybrid Cognitive Gaussian Relay Channels

说明：  可实现TCP/IP连接后数据的读取与写入(TCP/IP data read and write)

LDPC校验矩阵生成、高斯消去法编码、BP译码程序，可以作为自己编写LDPC编译码程序的参考。因为matlab代码效率不高，所以这个程序仿真起来比较慢.(LDPC check matrix generation, Gaussian elimination coding, BP decoding procedure can be used as its own procedures for the preparation of LDPC codec reference. Because matlab code efficiency is not high, so this process is relatively slow simulation together.)
