Blind multi-user detection based on unscented particle filter in asynchronous CDMA system
摘要
Abstract
Aiming at the problem of high bit error rate in blind multi-user detection in asynchronous CDMA system,according to the characteristics of unscented particle filter and asynchronous CDMA, blind multi-user detection methods are proposed based on unscented particle filter.The simulation is carried out under the flat Rayleigh fading channel and its results show that unscented particle filter can get higher detection accuracy than traditional particle filer.Under the condition of user number increasing and the power of interference user changing unscented particle filter still shows better performance.There-fore the method is prior to traditional particle filter in detection performance and anti-interference ability.关键词
