This paper deals with the capacity behavior of wireless Orthogonal Frequency Division Multiplexing
(OFDM)-based spatial multiplexing system when considering realistic channel delay profiles.
In both the SISO and the MIMO contexts, we compare the

Abstract—A generalised spatial modulation (SM) scheme with
multiple active transmit antennas, named as multiple activespatial
modulation (MA-SM), is proposed in this paper. By allowing
multiple transmitting antennas in the SM system to transmit

Trellis coded modulation (TCM) is a well known
scheme that reduces power requirements without any bandwidth
expansion. In TCM, only certain sequences of successive
constellation points are allowed (mapping by set partitioning).
The novel idea
