Alternative good LDPC codes for DVB-S2(In our following paper, we find that the shortten codes of DVB-S2 have some problems,this program can provide a good DVB-S2 LDPC code without cascaded BCH codes.

对原始信号进行四相相移键控调制，然后加入高斯白噪声，对加噪信号进行解调，对比解调信号与原始信号，计算误码率(The original signal quadrature phase shift keying modulation, and then adding Gaussian white noise, plus noise signal is demodulated, comparing the demodulated signal with the original signal, bit error rate calculation)

说明：  采用元胞自动机算法模拟传染病传染治愈过程，在60天后加入隔离,病情100天后得到控制(Cellular automata algorithm was used to simulate the process of infectious disease cure. After 60 days, the disease was isolated and controlled after 100 days)
