Haibin Zhang

Open publisher page 0 citations

Abstract

This paper introduces the main thought of Hungarian subcarrier allocation algorithm in multi-user MIMO-OFDM systems,and then puts forward a partial-optimal subcarrier allocation algorithm to reduce the computation complexity and makes a comparison with Hungarian algorithm.Simulation results show that the computation complexity is decreased greatly while the total data-rate is lessened slightly.The resource allocation efficiency is improved,which meets the demand of real-time allocation of high rate wireless systems.
