《通信系统仿真原理与无线应用》MATLAB源代码，在pudn网上也看到有这个代码，但是那个不全，有好几章代码没有，这个完整版的。(Communication System Simulation principle and wireless applications. "MATLAB source code, in pudn online to see this code, but incomplete, Several chapters code is not the full version.)

matlab下的LDPC仿真,高斯信道，调制方式为QPSK(A simulation of LDPC on matlab)

说明：  交叉小波分析，用于气象、水文数据的分析等。(Cross-wavelet analysis for meteorology, hydrology, etc.)

说明：  解决正定盲源分离方法，基于负熵的独立成分分析(Solve positive-determined blind source separation methods, independent component analysis based on negative entropy)

该模块实现了对转永磁同步电机的矢量控制，保证了两转子转速相等(this mode is something about anti-rotary PMSM control)

采用形态滤波器去除噪声，分别采用eemd、形态滤波器小波去噪等方法去噪，并对比(choose Morphology filters for analyzing roller bearing fault signal, and compared to the EMD EEMD WT METHODES)

说明：  DPSK、QPSK、OQPSK Matlab设计实现(DPSK, QPSK, OQPSK Matlab Design and Implementation)

说明：  根据奇异值分解出来的奇异值，画出奇异值分布曲线，根据公式算出奇异值的突变点，此时突变点即是VMD分解分量数的K值(According to the singular value decomposed by singular value, the distribution curve of singular value is drawn, and the mutation point of singular value is calculated according to the formula. At this time, the mutation point is the K value of the decomposition component number of VMD)

关系JPEG在matlab中的一些应用，给大家使用(JPEG relations in matlab some applications, to the use of U.S.)

说明：  matlab实现的信道指标计算求误码率低的信道(Calculation of channel index realized by MATLAB to find the channel with low bit error rate)
