A new multiple‐input multiple‐output system, referred to as transceive spatial modulation (TRSM), which integrates transmit spatial modulation (SM) and receive SM. In the TRSM system, information bits are carried by the conventional amplitude–phase modulation as well as by the indices of both the transmit and the receive antennas. To improve the bit‐error‐rate performance, block Markov superposition transmission (BMST) is applied to the TRSM, resulting in BMST‐TRSM, where BMST is a recently proposed coding scheme and can be easily designed according to the spectral efficiency requirement. To reduce the computational complexity, a layered (suboptimal) soft detection algorithm is presented, which delivers a list of candidate spatial points (antenna combinations) first. Numerical results show that the proposed TRSM system performs well over the Rayleigh fading channels.
