说明：  偏最小二乘法中的交叉有效性计算的matlab程序，怎么计算出来的预测误差平方和PRESS不太对，偏大；()

傅里叶算法，用MATLAB编程，采样周期12个点。可以实现输入变量电压或电流h12个点，计算出电压或电流的有效值(Fu Liye formula;MATLAB programming; calculation)

数据包传送源码程序，小波包分析提取振动信号中的特征频率，分形维数计算的毯子算法matlab代码。( Data packet transfer source program, Wavelet packet analysis to extract vibration signal characteristic frequency, Fractal dimension calculation algorithm matlab code blankets.)

本程序用于完成BPSK、QPSK、8PSK的调制仿真。并可任意扩展到MPSK和MQAM。程序分成三个部分：phase.m对基带码元序列进行脉冲成型，可选矩形脉冲，升余弦脉冲和平方根升余弦脉冲； model.m 为主程序，完成各种信号的基带星座图映射、脉冲成型和调制； command.m给出一个简单的频谱显示测试。(This procedure for the completion of BPSK, QPSK, 8PSK modulation simulation. Arbitrary and may be extended to MPSK and MQAM. Program is divided into three parts: phase.m symbol of the baseband shaping pulse sequences, optional rectangular pulse, the square root raised cosine pulse and raised cosine pulse model.m-based procedures, completed a variety of base-band signal constellation mapping , pulse shaping and modulation command.m given spectrum shows a simple test.)
