摘要
循环冗余校验(CRC)由于其误码检测能力强,抗干扰性能优异,在众多的通信协议中得到广泛的应用。这里简要介绍了CRC编码算法的基本原理,在串行CRC编码基础上详细推导了CRC编码的并行计算原理,给出了该算法详细的软件实现过程,通过仿真验证了该算法的正确性和可行性,CRC并行算法大大提高了编码速率。
Owing to its extraordinary error code checking and anti -jamming abilities, cyclic redundancy check （CRC） finds the widest applications of all communication protocols. In this paper, the basic principle of CRC coding algorism is briefly introduced, and based on serial CRC coding, the principle of parallel coding is deduced. The software realization of this algorism is described in detail. Simulation results show that the algorism is valid and feasible with a significant improvement in coding speed.
