The concepts of the normalized bandwidth and the normalized signal-to-noise ratio are defined,which are used to construct the plane model.Based on the model,a method of measuring the overall resource efficiency of the MIMO-OFDM system is proposed.This method obtains the overall resource efficiency of the MIMO-OFDM system under different detection algorithms and different modulation.The main conclusion is that the MIMO-OFDM system with the maximum likelihood detection algorithm has the relatively high overall resource efficiency,and using M-ary quadrature amplitude modulation(MQAM)has higher overall resource efficiency than employing M-ary phase shift keying(MPSK)while its overall resources efficiency improves with the increase of M.
