Optimising MIMO DFE for systems with spatial loading

Abstract: In this paper we consider transmission over MIMO channels with channel state information available at the transmitter. This enables an optimization of the rate and power distribution over the parallel subchannels in the transmission system (loading). We show that spatial loading provides substantial gains and give an algorithm to calculate the matrix filters required for decision feedback equalization (DFE) in systems with loading. Introduction-We study the transmission over MIMO channels, described in the dis… Show more
