在原LLR停止准则的基础上通过设置一个最小计算门限（Imin-computation）提出一种新的可变迭代译码方案,即简化的LLR停止准则（Simplified LLR Stopping Criterion）。简化的LLR停止准则与原LLR停止准则相比,不仅能减少大量的计算,而且仿真结果表明,简化的LLR停止准则还拥有跟原LLR停止准则相似的平均迭代次数性能,并且能获得更好的误比特率（bit-error-rate,BER）性能。当误比特率为10-6时,简化的LLR停止准则与原准则相比,能获得大约0.1dB的性能增益。

This paper proposes a new variable iterative decoding scheme named the Simplified LLR Stopping Criterion,by setting a minimum computation threshold（Imin-computation） based on the original LLR stopping criterion.The proposed new scheme can not only greatly reduce the amount of computation of the receiver,but also can get similar average iteration numbers.What＇s more,the new criterion can achieve better performances in terms of BER（bit-error-rate） compared with the original LLR stopping criterion.Simulation results show that when BER is at 10-6,the new criterion can get about 0.1dB coding gains than the original LLR stopping criterion.
