中文说明：FIR 底通和带通滤波器和IIR 底通和带通滤波器，LDPC码的完整的编译码，最小均方误差（MMSE）的算法，真的是一个好程序，加入重复控制，通过反复训练模板能有较高的识别率。
English Description：
Fir at the end of pass and bandpass filters and IIR bottom pass and band-pass filter, the encoding and decoding of LDPC codes, the minimum mean square error (MMSE) algorithm, really is a good program, the repetitive control is introduced. Through repeated training pattern can have higher recognition rate.
