Research on Method of DS-CDMA Despread Filter Optimization

摘要：

It has been proved that multiple access interference is mainly influence factor for the capacity of systems in DS-CDMA.This paper designed how to utilized Least Mean Square (LMS) arithmetic process iterative calculating for filters coefficient,and then acquired filters coefficient that based on least mean squares error for achieved final optimize to filter.For achieved final optimize to filter,LMS arithmetic has been utilized that process iterative calculating for filters coefficient,and then acquired filters coefficient that based on LMS error.Using LMS arithmetic,dispreading filter of DSCDMA system was optimized,and then acquired best matched filter.Based on this method,MAI was suppressed.
