Overview

abstract

• This paper proposes a novel scheme to transmit signals in a downlink multiuser multiple input-multiple output scenario. The proposed scheme combines spatial shift keying modulation and orthogonal Walsh codes. Analytical and simulation results show that the proposed scheme has performance gains of 10–11 dB for an average bit error probability of 10−3 when compared to the conventional channel inversion scheme. In addition, it has the advantage of not requiring channel state information in the transmission whereas only a single RF chain is used. Compared with the previous MU-SM scheme, the proposed scheme has performance loses of 4–5 dB approximately; however the detection complexity is reduced up to 93 %25 for the analyzed cases. © 2016, Springer Science%2bBusiness Media New York.
