On media-based modulation using RF mirrors

Abstract

Media-based modulation (MBM) is a recently proposed modulation scheme which uses radio frequency (RF) mirrors at the transmit antenna(s) in order to create different channel fade realizations based on their ON/OFF status. These complex fade realizations constitute the modulation alphabet. MBM has the advantage of increased spectral efficiency and performance. In this paper, we investigate the performance of some physical layer techniques when applied to MBM. Particularly, we study the performance of i) MBM with generalized spatial modulation (GSM), ii) MBM with mirror activation pattern (MAP) selection based on an Euclidean distance (ED) based metric, and iii) MBM with feedback based phase compensation and constellation rotation. Our results show that, for the same spectral efficiency, GSM-MBM can achieve better performance compared to MIMO-MBM. Also, it is found that MBM with EDbased MAP selection results in improved bit error performance, and that phase compensation and MBM constellation rotation increases the ED between the MBM constellation points and improves the performance significantly. We also analyze the diversity orders achieved by the ED-based MAP selection scheme and the phase compensation and constellation rotation (PC-CR) scheme. The diversity orders predicted by the analysis are validated through simulations.

Investigation of Sphere Decoder and Channel Tracking Algorithms for Media-Based Modulation over Time-Selective Channels

“…In such system, each transmit unit can create = 2 MBM independent channel states by turning on/off MBM RF mirrors. By employing the GSM-MIMO model described in [12], the received signal at the receiver can be expressed as…”

“…It is shown in [4] that proposed schemes achieve considerably better error performance than the existing MBM systems.

Transmit Antenna Subset Selection for Single and Multiuser Spatial Modulation Systems Operating in Frequency Selective Channels

“…Recently, Sun et al [28] have proposed a reduced-dimensional ED-TASequivalent criterion, which results in the same performance as that of ED-TAS, albeit at a reduced complexity. In [29], Naresh et al have studied the ED based mirror activation pattern selection schemes in the context of RF-mirror aided spatial modulation systems. In [30], the authors have proposed a generalized transmit and receive diversity condition for …”
