很好用的matlab批量修改文件名的程序(The good use matlab bulk modify the file name of the program)

说明：  matlab实现数字调频与解调，并进行结果显示。(matlab digital FM demodulation, and display the results.)

说明：  matlab中应用BP神经网络对模式识别的源码(matlab application of BP neural network for pattern recognition of the source)

在matlab中利用平方环实现QPSK信号的码元同步，可实现，效果较好。(Square ring QPSK signal symbol synchronization can be achieved in matlab better.)

This code is used in the course Digital Communications. It simulates 16QAM mode with different SNRs.

通过Matlab编程，经过提取特征参数与模板对比，可以识别0-9十个数字。(By Matlab programming, after extracting characteristic parameters compared with the template, you can identify 0-9 ten numbers.)

说明：  采用牛顿拉夫逊法计算电网的潮流，各节点电压，各支路电流。(Newton Raphson power flow calculation, and each node voltage current in each branch.)
