Summary :

This paper presents a simplified maximum likelihood detection (MLD) scheme for multiple-input and multiple-output spatial division multiplexing (MIMO-SDM) systems. In the scheme, ordered successive detection (OSD) is applied to multiple symbol candidates retained in the preceding stage to limit the number of symbol vector candidates. Accordingly, the subsequent MLD searches for the most likely signal vector among the limited symbol-vector candidates. Simulation results demonstrated that the proposed scheme provides the bit error rate performance close to that achieved by MLD while reducing the computational complexity.
