摘要
提出了一种制表映射的BCH纠错解码和校验方法,通过对RNSS-ICD文档北斗导航电文BCH编码的深入理解,设计出了一种占用CPU资源少、实现简单方便的制表映射的编码和纠错解码算法,减小了算法在实现时对CPU和内存资源的占用;给出了一种再编码校验的校验方法仿真验证了该算法的准确性和可靠性,保证导航电文的可靠性;对提高接收机的性能具有很强的工程适用价值。
Presents a tabulation of the BCH error correction decoding and parity method,Based on RNSS-ICD document Beidou navigation message BCH code of understanding,design a CPU resources,occupy fewer simple tabulation mapping coding and decoding algorithm for correction.The algorithm in achieving reduced CPU and memory resources when the occupation.Gives a kind of calibration method coding calibration algorithm simulation verifies the accuracy and reliability,guarantee the reliability of the navigation message.Simulation of the algorithm accuracy and reliability,to improve the performance of the receiver has a strong application of value engineering.
