Balanced Power Control in Uplink MIMO-OFDM System

This paper presents a balanced power control scheme for the uplink of cellular MIMO system. The problem of coordinating power consumption reduce with raise in capacity simultaneously is formulated and an efficient algorithm with good performance is derived. Convex optimization method is used to solve the question. In this paper, an adaptive power allocation scheme is proposed by using interior-point method. Simulation results show that the proposed approach, compared to the optimal water-filling algorithm, actually achieves significantly lower total power consumption with similar performance in throughput.
