基于置信度判定的循环冗余校验纠错技术
Error Correction using Cyclic Redundancy Check Based on Confidence Declaration
【摘要】 以S模式下行数据链的检纠错为例,给出了基于置信度判定的循环冗余校验多位纠错技术,实现了突发和随机分布的多位差错的纠正,在不增加冗余码的情况下大大增强了循环冗余校验码的纠错能力。
【Abstract】 Taking the Mode S down datalink processing as example,this paper introduces two multi-error correction methods using cyclic redundancy check based on bit and confidence declaration: one for correcting burst errors,the other for correcting random errors.Both techniques enhance the error correcting ability of cyclic redundancy check.
