本文通过对多维奇偶校验码的纠错效果进行定量分析计算,得出了纠错效果依赖于原始误码率 P_0及校验维数 Q 的数量关系。并分析得出有用的推荐值 Q=4,已经能够很好地满足现行典型通信线路误码率 P_0≤10~(-5)的使用。而且为最小时间和空间复杂性的硬件实现提供了决策依据。
In this paper, the quantitative analysis and calculation of the error correction effect of multi-dimensional parity codes shows that the error correction effect depends on the relationship between the original bit error rate P_0 and the check dimension Q. And the useful recommendation value Q = 4 has been analyzed, which can well meet the use of the current typical communication line with bit error rate P_0≤10 ~ (-5). But also provides the decision-making basis for the hardware implementation of minimum time and space complexity.
