Parallel stack decoding for MIMO schemes

Abstract

Classical ML decoders for multiple input multiple output (MIMO) systems like the sphere decoder, the Schnorr-Euchner algorithm, the Fano and the stack decoders suffer from high complexity for high number of antennas and large constellation sizes. In this paper, we propose the use of parallel processing for stack decoding, to decode signals transmitted on linear MIMO channels to reduce time consumption of hardware architecture. It will be shown that the parallel stack decoder allows a 50% less of run time compared to the classical stack decoder.
