遗传算法程序，很实用，高人编程。有详细的程序注释，可以供参考(It compares the effects of early warning using BP Neural Network before and after the rank sum test, sampling the listed companies in Shenzhen and Shanghai SecurityMarkets. The results showthat BP neural net- work model has good application value to the warning for financial distress of China’s listed companies. Especially, )

说明：  Accumulator-Based Raptor Encoding and Decoding

OFDM系统通过在时域符号前插入大于信道冲击响应长度的循环前缀（CP）可以避免符号间干扰(ISI)和载波间干扰(ICI)。但是，过长CP会使得数据传输效率降低。可以采用最小均方误差（MMSE）信道缩短均衡技术来压缩信道冲击响应长度。(OFDM systems avoid inter-symbol interference (ISI) and inter-carrier interference (ICI) by inserting a cyclic prefix (CP) larger than the channel impulse response length before the time-domain symbol. However, long CP will reduce the efficiency of data transmission. A minimum mean square error (MMSE) channel shortening equalization technique may be employed to compress the channel impulse response length.)
