一种改进的循环冗余校验纠错技术
Modified Error Correction Using Cyclic Redundancy Code

摘要: 通常传统上使用蛮力纠检错的方法来纠正接收数据中存在的随机错误.现以ADS-B的S模式数据链为例，分析了蛮力纠错方法在实践应用中存在的局限和不足，并根据这些局限和不足给出了一种纠错预处理的方法，将这种方法结合蛮力纠检错方法使用，在不改变编码的情况下大大增强了循环冗余校验码的纠错能力.Abstract: Traditionnally brute force technique is used to correct these random errors that receiving data usually contain.Taking the ADS-B as example,this paper analyzes shortcomings of brute force technique.In order to make up for the shortage of the brute force technique,a method of preprocessing is proposed.Both techniques enhance the error correcting ability of cyclic redundancy check.
