The performance of adaptive multielement decision feedback equalization (DFE) receiver structures is examined for a narrowband, two-user space division multiple access (SDMA) system with a TDMA slot structure similar to that of the Digital Advanced Mobile Phone Service (DAMPS). Various means of coupling or cross-feedback of decisions between user receiver sections at the base station are explored, as well as a slot-to-slot adaptive receiver structure. It is found that the cross-feedback of
