| 摘 要： | 针对直扩码分多址通信系统中存在的多址干扰抑制问题，采用加入动量项加快算法收敛的方法，提出一种基于动量抖动符号误差的恒模盲多用户检测算法，在理论上证明该算法的收敛性。通过计算机仿真对该算法与其他算法进行比较，结果证明该算法有较好的收敛性、跟踪性和鲁棒性。

| Abstract: | Aiming at the problems of suppressing multi-access interferences in direct sequence code division multi-access system, this paper proposes a constant modulus blind multi-user detection algorithm of momentum dithered signed-error by adding momentum to fasten convergence speed, and its convergence is theoretically proved.Result that it compares with other algorithm by computer simulation shows that it obtains better convergence tracking and robustness properties. |
