Abstract

Abstract—In this letter, we investigate the effects of training-
based channel estimation on the achievable performance of
the recent spatial modulation (SM) based multiple-input mul-
tiple-output (MIMO) scheme. This is motivated by the fact that
the SM transmitter is constituted by a single radio-frequency
(RF) branch and multiple antenna elements (AEs), hence simul-
taneous pilot transmissions from the AEs are impossible, unlike
in the classic multiple-RF MIMO transmitters. Our simulation
results demonstrate that the SM scheme’s BER curve exhibits
a performance penalty, while relying on realistic imperfect
channel-estimation. In order to combat these limitations, we pro-
pose two single-RF arrangements, namely a reduced-complexity
joint channel estimation and data detection aided SM scheme
as well as a non-coherently detected single-RF space-time shift
keying scheme dispensing with channel estimation.
