摘要

研究了多小区异步CDMA系统的序列自适应问题。我们提出了一种新的干扰度量，反映了用户之间的实际相关性。证明了该系统存在纳什均衡。我们还提出了一种分布式序列自适应方案，该方案为我们提供了比现有系统更大的增益。值得注意的是，在该宏分集系统中，最优序列的MMSE接收器通常不等于匹配的滤波器。

Sequence adaptation for cellular systems

We consider the sequence adaptation problem for multi-cell asynchronous CDMA systems. We propose a new interference measure that reflects the actual correlation between users. It is shown that Nash equilibria exist in such system. We also propose a distributed sequence adaptation scheme that provides us a significant gain over the existing systems. It is also remarkable that in this macro-diversity system, the MMSE receivers for the optimal sequences are not equal to the matched filters in general.
