摘要
在分析基于循环冗余校验码纠正单比特错误和基于CRC/BCH混合编码方法的基础上,提出了一种多位纠错算法,在一定的信噪比范围内分析了算法的纠错性能和对吞吐量的改善情况,算法降低了传输数据的误码率和误帧率,提高了系统的吞吐量。对纠错算法的能耗进行了分析比较,与ARQ方案,BCH纠错方案的能耗进行了对比,在一定的范围内算法有较高的能量利用率。
A multiple bits error correction algorithm based on the analysis of cyclic redundancy check code correcting single bit error and mixed error control coding algorithm is proposed. The performance of error correcting of the algorithm and throughput improvement was analyzed, in certain range of SNR. The algorithm can reduce the error code rate and frame error rate effectively, and also improve the network performance by improve throughput of system. The energy consumption of the algorithm is analyzed. Through comparing with the method of ARQ and BCH error correction,this algorithm has high energy efficiency in certain range.
