Good instructions for the beginners of MPI programming. It holds all the basics.

函数通过输入信号序列和函数序号，以及调制解调选择参数来完成扩频调制解调。original_seq是原始输入序列，可能是未调制序列，也可能是调制序列，walsh_num是walsh函数的序号，select选择对输入的序列进行调制还是解调。(function through the input signal sequence and function of the serial number and choice of modulation and demodulation parameters to complete spread spectrum modulation and demodulation. Original_seq is the original input sequence may not be modulated sequence, and may also be modulated sequence, walsh_num walsh function of the serial number, select choice of input sequence modulation or demodulation.)

该函数是常用于求解采样信号的起点的matlab函数(matlab function used for the start point of signal)
