实现LDPC码校验矩阵的构造，采用Mackay 1A方法(Implementation of LDPC code check matrix construction uses Mackay 1A method)

说明：  使用Lenet网络对手写数字进行识别，识别效果比较好(Recognition of handwritten numerals by using Lenet network has better recognition effect.)

在瑞丽衰落 =信道下，对信号进行qPSK调制(qpsk for relaygh channel)

说明：  雷达动目标检测仿真，含脉冲压缩，mtd处理等(Radar moving target detection simulation, including pulse compression, mtd processing, etc.)

D2D通信实现资源分配算法的有关代码，用于提高下一代蜂窝网络中的频谱利用率的解决方案是设备到设备D2D(Device to Device）通信。(D2D communication implements code related to resource allocation algorithms. The solution for improving spectrum utilization in next generation cellular networks is device-to-device D2D (device-to-device) communication.)

该程序实现了去除图像中小于阈值的部分的代码。(The program has removed the image is less than the threshold part of the code.)

PAPR reduction in OFDM using PTS technique

自己需要给出坐标，GPS测距。主要是实现了基于maltab测距GPS测距原理(you should give coordinates, GPS ranging)

BPSK在OFDM系统不同信道下的误码率比较(This is a Script for computing the BER for BPSK in OFDM modulation in the AWGN channel.)
