| 摘 要： | 为了消除多用户的混沌通信系统中存在的多径信道畸变、多用户干扰以及信道噪声,组合不同的状态空间模型,提出了一种双扩展卡尔曼滤波器(Dual Extended Kalman Filter,DEKF)的盲均衡算法。仿真结果表明,这种盲均衡算法能较快地跟踪多径时变信道,有效地抑制信道噪声,进而实现多用户通信。

| Abstract: | In order to cancel channel distortions,inter-user interference,and channel noise,a dual exended Kalman filter(DEFK) algorithm combining different state space models for chaotic communication systems with muliuser was proposed.Simulation results demonstrate that the proposed method can fast track the coefficients of multipath fading channel and effectively reduce the channel noise in the realization of the multiuser communications. |
