Fractional media-based modulation with golden angle modulation

Abstract

One of the main drawbacks in the use of reconfigurable antennas for index modulation (IM) is the need to obtain an integer power of two number of uncorrelated channel realizations. In this study, we present media-based modulation with golden angle modulation (GAM-MBM) scheme as a new solution to this fractional bits problem by using symmetrical structure of golden angle modulation (GAM). We present a comprehensive overview of the fractional bits problem in spatial modulation (SM) and media-based modulation (MBM) and we show that the proposed scheme can be considered as a candidate for the next generation technologies with its versatile structure, which can be easily integrated into various concepts. Simulation results also show that GAM-MBM exhibits significant improvements in error performance over the existing fractional bits solutions.
