Set partitioning to construct block coded modulation with the presence of spatial modulation in MIMO systems

Abstract EN

In this paper, enhancing the BER performance of multiple-input multiple-output systems (MIMO) is considered by using Block Coded Spatial Modulation (BCSM).

It is a combination of Block Coded Modulation (BCM) used set partitioning to formulate the code, and the spatial Modulation (SM) as a transmission technique of MIMO systems.

To achieve this, the idea of MIMO communication systems, block coded modulation, set partitioning, multi stage decoding and spatial modulation have been combined.

Matrix Laboratory (MATLAB) is used for the simulation and Bit Error Rate (BER) is obtained and verified.

The simulation results for the combination of BCM with SM show that there is a significant improvement in BER performance compared to the classical SM techniques.

It gives an approximately 5 dB enhancing of BER performance from the use of SM only, and about 3 dB enhancing from the use of coded information bits with SM.
