The paper proposes a novel TRIS transmitter-enabled spatial modulation (SM) MIMO system. Key highlights:
The TRIS transmitter activates specific column elements per time slot, while the receiver uses maximum likelihood detection.
The authors derive closed-form expressions for the upper bounds of the average bit error probability (ABEP) using both vector-based and element-based approaches.
Asymptotic ABEP expressions and diversity gain analysis are provided.
To improve performance, the authors optimize the ABEP with a fixed data rate constraint.
A simplified improved TRIS-SM scheme is proposed to reduce computational complexity.
Simulation results validate the theoretical derivations and show the proposed TRIS-SM scheme outperforms conventional SM, while the improved TRIS-SM scheme further improves reliability.
