Hybrid Multiple-Input Multiple-Output OFDM Index Modulation for 5G Wireless System

Dr. K. O. Joesph | G. Valarmathy [2] | A. Rajeshwari


Abstract: - Multiple-input multiple-output (MIMO) based index modulation has the advantage of high data rate and low complexity transmission and has great attention now a days. At the same time due to invention of digital video broadcasting 16-QAM and 64-QAM schemes are widely used in wireless systems. In this paper we introduce a novel low-complexity signal detector enabled multiple-input multiple-output (MIMO) detector with IM systems, suitable for efficient low complexity system with tolerable error rate. The actual IM methods has no diversity gain which causes a significant reduction in the system performance. In this paper to eliminate the bad effects of the channel assignment of the IM, novel ML based MIMO systems with index modulation technique (ML-MIMO-IM) is proposed. Here the efficient hybrid ML sub detector system is used to achieve superior performance compared to the conventional MIMO detectors. The performance of the proposed design is close to the existing MIMO scheme, while resulting in a significantly lower complexity. The efficiency of MIMO over high order constellations are verified through MATLAB BER simulation and complexity reduction is also proved to be an efficient one.
