Abstract
In this paper we propose and analyze an adaptive spatial modulation scheme for MIMO-OFDM systems which adoptively and optimally selects one of the following transmission modes: diversity, spatial multiplexing and a hybrid combination of these two modes. Two criteria are used for mode selection, namely, the minimum Euclidean distance and a simple threshold based stochastic method exploiting channel quality estimations. We consider practically implementable antenna configuration with four transmit antennas and two or four receive antennas. Simulation results show that considerable BER performance gains can he obtained by the adaptive spatial modulation system, as compared with systems based on fixed modulation schemes.
