Abstract

The undetected error probability is an important measure to assess the communication reliability provided by any error coding scheme. Two error coding schemes namely, Joint crosstalk avoidance and Triple Error Correction (JTEC) and JTEC with Simultaneous Quadruple Error Detection (JTEC-SQED), provide both crosstalk reduction and multi-bit error correction/detection features. The available undetected error probability model yields an upper bound value which does not give accurate estimation on the reliability provided. This paper presents an improved mathematical model to estimate the undetected error probability of these two joint coding schemes. According to the decoding algorithm the errors are classified into patterns and their decoding result is checked for failures. The probabilities of the failing patterns are used to build the new models. The improved models have less than 1% error with respect to the simulation results and reflect in up to 60% higher mean time to failure as compared to available models.

改进了JTEC和JTEC- sqed编码方案的未检测错误概率模型

未检测到的错误概率是评价错误编码方案通信可靠性的重要指标。两种错误编码方案，即联合串扰避免和三重纠错(JTEC)和JTEC与同时四重错误检测(JTEC- sqed)，提供串扰减少和多比特纠错/检测功能。现有的未被检测到的误差概率模型产生了一个上界值，它不能对所提供的可靠性给出准确的估计。本文提出了一种改进的数学模型来估计这两种联合编码方案的未检测错误概率。根据译码算法对错误进行分类，并对其译码结果进行检查。失败模式的概率被用来建立新的模型。与仿真结果相比，改进的模型误差小于1%，与现有模型相比，平均故障时间提高了60%。
