Abstract

The adaptive modulation is an important effective technique, which can be applied in the multiple-input-multiple-output (MIMO) system to achieve a high average spectral efficiency. In this paper, an adaptive minimum transmit power modulation scheme under constant data rate and fixed bit error rate (BER) for the spatial MIMO system is proposed. It adjusts the modulation order and allocates the transmit power to each spatial subchannel when meeting the user´s requirements at the cost of minimum transmission power. Computer simulation results present the efficiency of the proposed scheme
