SELECTING IN STOP AND GO DECISION-DIRECTED ALGORITHM AND ITS MOMENTUM ALGORITHM

摘要

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 goDD算法的收敛速度,提出了一种自适应动量stop and goDD算法。该算法比stop and go算法的收敛速度更快。

Abstract: 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.
