Optimal power control for CDMA systems in the wideband limit

Traditional methods for solving multiuser control problems in CDMA systems do not scale well as the number of users in the system increases. To address this problem we develop a wideband limit approximation for dynamic programming problems in CDMA systems. This approximation greatly simplifies the state space and evolution equations for the users in a CDMA cell, thereby simplifying the optimal control problem. This wideband convergence result holds for a number of different linear multiuser receiver structures including the MMSE and matched filter receivers.
