MMSE_Receiver_for_DS-SS_in_AWGN_Channel

这段代码是基于pca方法的数字图像处理技术，具有实际用应价值(This code is based on the method pca digital image processing technology, with the actual values used should be)

第 一 类 第 一 类 修 正 贝 塞 尔 函 数(Modified Bessel function of first kind)

用MATLAB实现CCSDS_LDPC编码，并生成相应的校验矩阵H。压缩包内包含相应源程序以及CCSDS_LDPC编码原理的说明文档。(Using MATLAB CCSDS_LDPC coding, and generate the corresponding check matrix H. Compressed package that contains the corresponding documentation and CCSDS_LDPC source coding theory.)

坐标的3/2变化模块以及PARK CLARK 反变换(PARK/CLARK)

产生调频步进信号，再进行脉冲压缩，混频，最后进行高分辨率成像。本程序用于测距，参数可以进行修改。注释详细。(stepped LFM generating, and then pulse compression, mixing, and finally high-resolution imaging. The procedure used for ranging, the parameters can be modified. Detailed notes.)

滞环电流模块，可用于伺服电机来仿真使用，效果很好！(Hysteresis current module can be used to simulate the use of servo motors, the effect is very good!)

在1x1的单位矩形中随机部署传感器节点，而且假设每个节点的通信半径一样，要求利用蒙特卡洛算法进行1000次试验分别模拟出连通率随节点数增加以及通信半径增加的变化趋势。(Random units deployed in 1x1 rectangular sensor nodes, and assumed that the communication radius of each node, requires the use of Monte Carlo algorithm to simulate the 1000 trials were increased with the number of nodes increased connectivity and communication radius increasing trends.)

说明：  该文件可实现杨氏双缝干涉仿真，效果nice(This file can realize the simulation of Young's double slit interference, and the effect is nice)

dsb仿真，没有高斯白噪声的，可用！！！(dsb simulation, there is no white Gaussian noise can be used! ! !)
