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.
