In this paper, we present a performance and energy
efficiency comparison of the recently devised single RF Multiple-
Input-Multiple-Output (MIMO) concept of Spatial Modulation
(SM) with the conventional single-antenna transmission method
with receive Maximum Ratio Combining (MRC), which we
denote as single-antenna/MRC, for different types of fading
channels. In particular, the fading channels that are examined
are: i) Rayleigh, ii) Nakagami-
m
, and iii) Weibull. Results that
are based on Monte Carlo simulations show two main findings:
i) the severity of fading has a big impact on the relative signal-to-
noise (SNR) difference and energy efficiency gain between these
two schemes for a target average bit error probability (ABEP);
ii) the more severe the fading is, the more suitable SM tends
to be with respect to the single antenna/MRC, according to the
energy per bit required to achieve a particular low target ABEP. |
