摘要

本文研究了异步码间干扰(ISI)信道下多天线线性DS-CDMA接收机的盲(半盲)估计问题。我们介绍了接收器在符号速率和芯片速率之间的简单关系，并推导了确定性约束，可以用来在小样本量下以盲的方式确定这些接收器。芯片速率接收器显示为接近MMSE接收器。讨论了与现有技术的联系。

Blind chip- and symbol rate CDMA receivers

This paper deals with the problem of blind (and semi-blind) estimation of linear DS-CDMA receivers using multiple antennas in asynchronous intersymbol interference (ISI) channels. We introduce simple relations between receivers at the symbol rate and at the chip rate and derive deterministic constraints that can be used to determine these receivers in a blind manner, with small sample sizes. The chip rate receiver is shown to be close to the MMSE receiver. Connections with existing techniques are discussed.
