通信仿真的学习书籍，simulation中的仿真使用介绍，通信专业初学者适用(Communication simulation learning books, simulation simulation introduction, communication professionals, beginners apply)

lsb实现文本水印的嵌入与提取，真彩色图像也行！ 都是可以用的 位置放对就行！ 本人已调试过！(LSB implements the embedding and extraction of text watermarking, and true color image is also OK! All can be put in the right place! I have debugged!)

松组合导航源码，GPS原理及应用书上的，新测可用。(Loosly integrated navigation for GPS and MEMS-IMU, attached matlab codes and flying test data.These source codes come the book GPS applications and methods , they were tested and are avaliable absolutely.)

两种非参数估计方法 核估计 局部线性估计(kernel smoothing local constant regression )

DSP实现对内存卡写入的测试程序 能够准确的对内存卡进行写入操作 可在此基础上进一步开发内存卡(A Test Program for Memory Card Writing Based on DSP Can accurately write to memory card On this basis, memory card can be further developed.)

说明：  此代码为4ASK发送调制与接收解调的通信系统，为主要代码(Communication system of 4ask transmitting modulation and receiving demodulation)

说明：  极化码极化信道仿真，信道极化是信道合并与信道分裂两种信道操作的结果。在上述两种操作下，原本相同的N个W信道产生了极化现象，其中一部分信道的信道容量趋近于1，另一部分信道的信道容量趋近于0。(Channel polarization is the result of channel merging and channel splitting. Under the above two operations, the original n w channels have polarization phenomenon. The channel capacity of one part of the channel approaches to 1, and the channel capacity of the other part approaches to 0.)

本人做的GPS并行码捕获的算法.用的是1024点FFT,原始数据可以假如不同功率的噪声.(GPS parallel code acquisition algorithm. Using a 1024-point FFT. If the original data can be different noise power.)

说明：  利用伪随机序列作为发送信号，经过信道，产生了频偏和相位偏移，利用数字锁相环的原理实现对信号的频率估计和相位估计，实现信号的载波同步。(The frequency offset and phase offset are generated by using pseudo-random sequence as the transmitting signal through the channel. The frequency estimation and phase estimation of the signal are realized by using the principle of digital phase-locked loop, and the carrier synchronization of the signal is realized.)
