| 摘 要： | 盲自适应多用户检测器由于既能实时跟踪信道信息及用户信息,又不需要发送训练序列而成为研究的热点,但一般的盲自适应多用户检测技术存在收敛速度慢的弱点。提出一种基于MOE(最小输出能量)的盲自适应多用户检测器,通过合理地选取时变步长,可有效地提高多用户检测器的收敛速度,从而提高系统的性能。

| Abstract: | Blind adaptive multiuser detector has become a researchhotspot because it can not only track real-time information of channels and users, but also have no need of train sequences. But many blind adaptive multiuser detection algorithms involve low convergence rate. This paper presents a MOE based blind adaptive multiuser detector for CDMA systems. By reasonably choosing time varying step size, it can effectively improve the convergence rate so as toincrease the whole system performance. |
