Abstract	The spatial modulation (SM) divides input data into antenna indices and data symbols, and transmits data symbols via the specific antenna chosen by an antenna index. The performance of SM is affected by the worse one between the detection performances of antenna index and data symbol. In this paper, power efficient SM based transmitter and receiver architectures are proposed in order to provide different protection levels according to the important level of data, and also to improve the receive performance as compared with the conventional SM. To provide unequal error protection (UEP) at the transmitter, the antenna index and data symbol are separately encoded by two FEC codes. At the receiver, the two-stage detection and decoding based on a novel criteria is applied in order to enhance the bit error rate (BER) performance. Simulation results show that the proposed scheme outperforms the conventional SM over frequency selective channels.
