Generalised transmit–receive joint spatial modulation

Abstract

A generalised transmit-receive joint spatial modulation (GTRSM) scheme is proposed, which amalgamates both transmitter-and receiver-side spatial modulation (SM) schemes. The proposed GTRSM jointly employs the combinations of multiple instead of a single activated transmit and receive antennas and baseband symbols to transmit information. The optimal maximum-likelihood detector for GTRSM is formulated, and the channel capacity of GTRSM is also analysed. Simulated results demonstrate that the proposed GTRSM behaves good BER performance and can significantly improve the channel capacity compared with conventional SMs.

Performance analysis of cooperative wireless sensor network with index‐based modulation

“…In this paper, the performance of the cooperative WSN in association with SM (CoSM) and enhanced SM (CoESM) is compared. It conveys information bits not only by the index of the active antenna, and also by the constellations transmitted from each of them [5]. CoESM achieves a substantial performance gain over conventional CoSM.…”
