Multiple-Symbol Detection Aided Differential Spatial Division Multiple Access

This paper presents a Multiple-Symbol Differential Spatial Division Multiple Access (MS-DSDMA) system conceived for low-complexity and high-bandwidth-efficiency applications operating in time-varying fading channels, where no channel estimation is required. A low-complexity adaptive Multiple-Symbol Differential Interference Suppression (MS-DIS) scheme is proposed, which is based on the Maximum Signal-to-Interference-plus-Noise Ratio (MSINR) criterion and facilitates the implementation of the powerful Multiple-Symbol Differential Sphere Detection (MSDSD). Then, a practical three-stage turbo DIS receiver design framework is proposed for the MS-DSDMA system, which is constituted by concatenating the adaptive DIS filter bank, the MSDSD and the channel decoder.
