Joint power control and subcarrier allocation in MC - CDMA systems - An intelligent search approach

Abstract

In this paper we consider the problem of frequency assignment and power allocation for multiple users in a MC-CDMA system when the channel is known at the transmitter. Two intelligent search algorithms (Simulated Annealing and Tabu Search) were applied to the framework to find solution to the joint optimization problem. Simulations showed that by applying the framework the optimizing algorithms are capable of providing good solutions within a reasonable amount of time. © 2008 Springer Berlin Heidelberg.
