摘要

RAKE接收机已成为CDMA系统中利用多径分集的实现架构。本文作者通过基于mmse的接收器重新审视了多径分集的利用，并展示了它们在移动无线电信道中有效充当RAKE合成器的能力。讨论了两种MMSE接收机结构，即LFSE(线性分数间隔均衡器)和FS-DFE(分数间隔决策反馈均衡器)。通过仿真对它们的性能进行了评价，结果表明了它们与RAKE接收机相比的优越性。

Autonomous CDMA multipath diversity receiver

RAKE receivers have been the implementation architecture used to exploit the multipath diversity in CDMA systems. The present authors revisit the exploitation of multipath diversity through MMSE-based receivers and demonstrate their capability to effectively act as RAKE combiners in mobile radio channels. Two MMSE receiver architectures are discussed, namely the LFSE (linear fractionally spaced equalizer) and FS-DFE (fractionally spaced decision feedback equalizer). Their performance is evaluated by simulation and the results indicate their superiority compared to the RAKE receiver.<>
