心电信号R波检测的函数，包括降采样，滤波，希尔伯特包络提取三个预处理步骤。其中R波根据阈值检测，相对不应期要根据具体信号适当调整.(ECG R-wave detection functions, including down-sampling , filtering, Hilbert envelope extracted three pretreatment steps. Wherein R wave detection based on a threshold , the relative refractory period should be adjusted according to the specific signal . )

脉搏波的数据以及特征提取，提取到最高点最低点，周期。可以看下。(Pulse wave data, and feature extraction, extract the lowest point to the highest point, cycle. You can have a look.)

在通讯系统中，可以计算一个信号的SNR,THD等(In communications systems, can calculate a signal s SNR, THD, etc.)

说明：  用matlab实现的BP神经自校正系统模型(Using matlab to achieve self-tuning of the BP neural system model)

说明：  这个程序是使用MATLAB对ofdm中的压缩扩张技术降低PAPR技术的仿真，程序仿了不同u值下的对PAPR的降低程度不同(that is a simulation of papr using matlab ,it is using u_law companding)
