摘要

基于"数据重用"的常模均衡算法可以用于解决短时突发信号的盲均衡问题

但是对于这类算法应用中重要特性的研究还需要进一步深入。首先对数据重复导致的误收敛特性进行了分析并给出了产生这种误收敛的约束条件;然后对短数据重用常模算法能够达到和无重复使用的长数据常模均衡相同稳态误差的条件进行了详细分析并给出了相应的结论。这些分析和结论对于该类盲均衡方法的应用非常重要

计算机仿真验证了这些分析和结论的有效性。

Abstract

The constant modulus blind equalization algorithm based on "data reuse" could be used to solve the problem of blind equalization of short burst signals

but its important properties hadn’t been studied.The ill-convergence caused by data reuse was analyzed and the restriction was given firstly

and secondly

the conditions of data reuse constant modulus algorithm reaching to the performance of long time signals equalization was analyzed in detail and gave the corresponding results.The validity of these analyses is proved by computer simulation.
