Sphere Decoding for Spatial Modulation Systems with Arbitrary Nt

Abstract

Recently, three Sphere Decoding (SD) algorithms were proposed for Spatial Modulation (SM) scheme which focus on reducing the transmit-, receive-, and both transmit and receive-search spaces at the receiver and were termed as Receiver-centric SD (Rx-SD), Transmitter-centric SD (Tx-SD), and Combined SD (C-SD) detectors, respectively. The Tx-SD detector was… (More)
