基于FEC的误插入控制

本文讨论了采用前向差错控制（ＰＥＣ）技术进行ＡＴＭ网上信元误插入控制的可能性，重点研究了ＡＡＬ１用于信元丢失和比特误码控制的编码方法。提出并分析了四种误插入控制算法。指出传统的ＲＳ码很难在误插入控制中充分发挥码的能力，因此建议了一类略为修正的首尾非零非线性码。研究表明这类码能充分发挥码的潜力，与原始ＲＳ码比较，有好得多的误插入控制性能。

Cell Misinsertion Control Based on FEC

The possibility to use FEC in cell misinsertion control for ATM network is studied in this paper. Special attention is given to the FEC scheme for bit errors and cell losses correction in AALI.Four different algorithms for misinsertion control are proposed.It shows that,the traditional RS codes can not support misinsertion control to their full capacity.A slightly modified nonlinear codes as Head and Tail Non-Zero Codes(HTNZC) are proposed. HTNZC can have its full capability in cell misinsertion control, hence has much better misinsertion control performance compared with the original RS codes.
