摘　　要：基于Kalman的盲多用户检测技术具有很好的抗多址干扰能力,收敛速度快,但是计算复杂度高。文章结合子空间原理,研究计算复杂度低且性能更优的基于子空间的Kalman盲多用户检测算法,并将此盲自适应检测算法应用于传统的Rake接收机,能更好地抑制无线信道的多径及多址干扰。Blind multiuser detection based on Kalman technology has good resistance to multiple access interference ability,fast convergence speed,but high computational complexity.this paper study which has low computing complexity and better performance of the Kalman blind multiuser detection algorithm based on subspace,and blind adaptive detection algorithm applied to traditional Rake receiver.It can suppress the multipath and multiple access interference of wireless channel better.
