Build the resource requirement plane by the normalized bandwidth requirement and normalized signal to noise ratio，overall resource efficiency measure method is put forward based on the bandwidth efficiency and energy requirement，the method is taken into the multiple-input multiple-output (MIMO) system，overall resource efficiency of the MIMO is analyzed system under a different number of transmit and receive antennas，different modulation and detection algorithm. To conclusion that MIMO system the efficiency of the overall resources than the traditional single-input single-output (SISO) system overall resource with high efficiency. When the number of transmit antennas is fixed，MIMO system resource efficiency increases with the increase of the number of receiving antenna; Using M-ary quadrature amplitude modulation (MQAM) overall resource efficiency is higher than that of employing M-ary phase shift keying (MPSK)，and the overall resource efficiency improve with the increase of M. Maximum likelihood detection (MLD) is the optimal detection algorithm，which overall efficiency of resources relatively high. The above conclusions verify the validity of the algorithm，the overall resource efficiency measure provide an important basis for applied to other system as well as new detection algorithm.
