摘要

采用多用户检测原理的先进接收机结构有可能通过补偿多址干扰，大幅提高DS-CDMA系统的性能并缓解近距离问题。在多径信道中，可以通过结合减轻衰落影响的分集技术进一步提高性能。本文通过仿真方法研究了双天线分集与DS-CDMA多用户检测相结合的优势。极化和空间分集作为基地台分集接收的潜在候选进行了研究。

Evaluation of dual spatial and polarization diversity reception for DS-CDMA multiuser detection

Advanced receiver structures that incorporate multiuser detection principles have the potential of substantially increasing the performance of DS-CDMA systems and alleviating the near-far problem, by compensating for multiple access interference. In multipath channels, performance can be further improved by incorporating diversity techniques that mitigate the effects of fading. This paper studies via a simulation approach the benefits of combining dual antenna diversity with DS-CDMA multiuser detection. Polarization as well as spatial diversity are examined as potential candidates for diversity reception at the base station.
