Abstract :
A distributed signature sequence adaptation scheme is considered for the downlink of a MC-CDMA system, wherein each mobile user selfishly adapts its signature sequences to improve its own performance using measurements at its location with no consideration to the performance of other users in the system. The convergence of such an adaptation scheme is shown using a game theory framework. That is, with any initial signature sequences in the system, the proposed adaptation scheme definitely converges to a set of signature sequences at which no user can further improve its own performance with individual adaptation.
