Abstract

We consider the sequence adaptation problem for cellular asynchronous code-division multiple-access (CDMA) systems. A game-theoretic approach is used to investigate the stability issues of distributed adaptation algorithms. It is shown that the Nash equilibrium may not exist for cellular CDMA systems if the traditional interference measure is used. In turn we propose a new interference measure which ensures system stability.
