一种基于盲自适应卡尔曼滤波的多用户检测器
Multiuser detector based on blind adaptive Kalman filtering
摘要
Abstract
With the purpose of solving the interference caused by the incompletely orthogonal spread spectrum waveform of direct sequence spread spectrum code division multiple access, a novel multi-user detection algorithm is proposed by applying Kalman algorithm to blind adaptive algorithm. By comparing the algorithm with the LMS and RLS algorithm, it is proved that the algorithm, with more dynamic tracking capability, better stability and faster convergence speed, can suppress multiple access interference more effectively.关键词
