摘要
本文在分析“stop and go”判决引导算法的基础上,提出了一种选取β的方法。该方法保证对不同的信号和信道“stop and go”判决引导(DD)算法都能快速收敛。为了提高“stop and go”DD算法的收敛速度,提出了一种自适应动量“stop and go”DD算法。该算法比“stop and go”算法的收敛速度更快。
Based on analysis of the 'stop and go' decision-directed (DD) algorithm, a method of selecting (3 is proposed, which guarantees the quick convergent characteristic of the 'stop and go' DD algorithm. In order to improve the convergent speed of 'stop and go' DD algorithm, the momentum 'stop and go' DD algorithm is proposed and then based on this, an adaptive momentum 'stop and go' DD algorithm is also proposed. Computer simulations show that the proposed techniques are very effective for the 'stop and go' DD algorithm.
