摘要：In this paper, a promising wireless communication concept which is termed as spatial modulation (SM) is considered. In particular the focus is on an interference scenario between SM multiple-input-multiple-output (MIMO) system and conventional spatial multiplexing (SMX) MIMO system. It has been shown that the interference caused by SM has a peculiar behavior. Since SM exploits the spatial position of the active antenna as an additional dimension for data transmission, the interference caused by SM system has no fixed interference subspace which can not be estimated accurately. Hence, conventional interference suppression techniques can not be applied accordingly. In this paper, we discuss this unique problem generated by SM system, and propose three methods to overcome the adverse effects caused by such interference.
