Spatial modulation for OFDM with linear constellation precoding
Direct application of spatial modulation (SM) for orthogonal frequency
division multiplexing (OFDM) systems does not realize the inherent
frequency diversity gain since information symbols are not spread over
independently-faded subcarriers. This paper investigates a new
transmission scheme that employs spatial modulation (SM) for each group
of subcarriers in OFDM. Specifically, OFDM symbols in each group are
passed through a precoder to maximize the diversity and coding gains,
while spatial modulation is applied in each group to convey more
information bits by antenna indices. Performance analysis and simulation
results are carried out to demonstrate the superiority of the proposed
scheme over a previously-proposed combination of SM and OFDM.
