| 摘 要： | 在讨论可变扩频增益多速率直接序列码分多址(DS-CDMA)系统信号模型的同时,为了保证该检测器能适用于多径衰落信道环境,提出了基于Kalman滤波的盲多速率多用户检测器,并给出了Kalman滤波算法的实现步骤与最大值合并过程.仿真结果表明,与现有的一些盲自适应多用户检测器相比,本文提出的检测器在多速率环境下具有更为好的抗多址干扰、抗多径干扰能力,且能更快地收敛.

| Abstract: | On discussing the signal model of variable spread spectrum gain multirate DS-CDMA system,this paper proposes a multirate blind multiuser channel estimation algorithm based on Kalman filter to guarantee it to adapt to multi-path fading channel.The implementation steps of the proposed algorithm and combination produce of maximum value are described in detail.Simulation results prove that,compared with other proposed detectors in multirate system,the proposed algorithm can attain better anti-multi-address inte... |
