摘要

DS/CDMA系统的容量基本上受采集子系统性能的限制;即在具有一定可靠性的情况下能够实现信号采集的最大用户数。本文提出了一种利用FIR自适应滤波器的新码采集方案，该方案明显优于基于匹配滤波器的方案。结果表明，该方法可以获得与误码率准则相同的容量。

PN code acquisition in CDMA systems using a MMSE adaptive filter

The capacity of a DS/CDMA system is essentially limited by the performance of the acquisition sub-system; i.e. the maximum number of users that can achieve signal acquisition with a certain degree of reliability. This paper presents a new code acquisition scheme utilizing an FIR adaptive filter that significantly outperforms matched filter based schemes. It is shown that the proposed scheme can achieve the same capacity obtained from the BER criterion.
