信道编码的相关源码,包括检错码,线性分组码,卷积码,Turbo码和低密度校验码(LDPC).-Source, channel coding error detection code, linear block codes, convolutional codes, Turbo codes and low density parity check code (LDPC).

计算输入字符串的CRC编码。CRC编码即循环冗余码，它是利用除法及余数的原理来作错误侦测的。-Calculate the CRC coding of the input string. The CRC encoder that cyclic redundancy code, which is the principle of the division and the remainder for error detection.
