On the stability of distributed sequence adaptation for cellular asynchronous DS-CDMA systems
Chi Wan Sung, Kin Kwong Leung · IEEE Transactions on Information Theory · 2003
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.
