//接收端的解码模块（可综合）

//在信号接收的刚开始发送端发送的是10个1信号，

//即10个+M序列，所以我们在开始时每接收到一个信号做一次累加运算

//当出现正的高峰时则认为达到同步，进入同步解调过程（mainbody）。

//也就是从此每进入一个信号就进行相应的相乘相加，

//在解接收到31个信号后进行一次判断，大于0认为接收到1，小于0认为接收到0。-//Receiver decoder module (which can be integrated)// at the beginning of the signal received by the sending end to send a signal 10,// that is, 10+ M sequence, so we at the beginning of each receive a signal for a cumulative computing// When the peak is reached when that synchronization, access to the process of synchronous demodulation (mainbody).// That is, a signal from each corresponding to the sum of the multiplication,// in the solution of 31 receive a signal after the judge, that the receiver is greater than 0 to 1, less than 0 that received 0.
