Abstract
We propose a bandwidth-efficient transmission scheme for multiple-input-multiple-output point-to-point and downlink channels. The bandwidth efficiency (BE) of spatial multiplexing (SMX) is improved by implicitly encoding information in the spatial domain based on the existence of constructive interference in the received symbols, which creates a differentiation in the symbol power. Explicitly, the combination of symbols received at a higher power level carries implicit information in the spatial domain in the same manner as that the combination of nonzero elements in the received symbol vector carries information for receive-antenna-based spatial modulation (RSM). The nonzero power throughout the received symbol vector for the proposed technique allows a full SMX underlying transmission, with the BE enhancement brought by the spatial symbol. Our simulation results demonstrate both significant BE gains and error probability reduction for our approach over the conventional SMX and RSM schemes.
