LDPC码的matlab仿真程序，希望对大家有用，不客气，(LDPC codes matlab simulation program, in the hope that useful, at worst,)

自相关检测方法是利用信号和噪声在相关域上的差别来构造检测器的。自相关检测是将信号与自身延迟一个时延后的信号作相关处理，或用双通道接收机的输出进行相关，得到扩频信号的自相关函数(Auto-correlation detection method is the use of signal and noise in the relevant field to construct the difference detector. Autocorrelation test is a time delay signal and its delayed signal for correlation, or the output of dual-channel receiver, associated, are spread spectrum signal autocorrelation function)
