Performance Assessment of a 3-D Encoded Spatial Modulation Aided Multicarrier MIMO Wireless Communication System

摘要

In this paper, a comprehensive study has been made to explore the suitability of spatial modulation (SM) transmission scheme to enhance performance of a 4×4 MIMO configured multicarrier wireless communication system. In such system, modern concatenated channel coding scheme utilizing Repeat and Accumulate (RA) and SPC Codes, MIMO-OFDM, MIMO-OFDMA with block type resource allocation, DFDMA (Distributed FDMA) and LFDMA (Localized FDMA) Subcarrier assignment and DFT-spreading have been used. With developed system performance evaluative simulator in perspective of BERs estimation using MATLAB, it is obserable from simulation results that 3-D encoded Spatial Modulation aided MIMO OFDMA wireless communication system shows robust performance in QAM digital modulation, Linear Minimum Mean Square Error signal detection and Distributed FDMA Subcarrier assignment schemes.
