In this letter, an ordered sphere decoding (OSD) algorithm for spatial modulation (SM) is proposed to reduce receiver complexity. The proposed algorithm relies on a developed matched filter (MF), where the initial solution vector is obtained and the transmit-antenna set is sorted, so as to perform a fast tree search. Furthermore, a threshold parameter is introduced to balance the tradeoff between complexity and performance. Simulation results show that the proposed SM-OSD algorithm achieves considerable complexity reduction compared to the SM-SD, especially in unbalanced multiple-input multiple output (MIMO) channels.
