Abstract

Modern-day applications of fifth-generation (5G) and sixth-generation (6G) systems require fast, efficient, and robust transmission of multimedia information over wireless communication medium for both mobile and fixed users. The hybrid amalgamation of massive multiple input multiple output (mMIMO) and orthogonal frequency division multiplexing (OFDM) proves to be an impressive methodology for fulfilling the needs of 5G and 6G users. In this paper, the performance of the hybrid combination of massive MIMO and OFDM schemes augmented with fast Fourier transform (FFT), fractional Fourier transform (FrFT) or discrete wavelet transform (DWT) is evaluated to study their potential for reliable image communication. The analysis is carried over the Rayleigh fading channels and M-ary phase-shift keying (M-PSK) modulation schemes. The parameters used in our analysis to assess the outcome of proposed versions of OFDM-mMIMO include signal-to-noise ratio (SNR) vs. peak signal-to-noise ratio (PSNR) and SNR vs. structural similarity index measure (SSIM) at the receiver. Our results indicate that massive MIMO systems incorporating FrFT and DWT can lead to higher PSNR and SSIM values for a given SNR and number of users, when compared with in contrast to FFT-based massive MIMO-OFDM systems under the same conditions.

Summary

Introduction

In this era, the requirement for systems that can support elevated data rates is becoming increasingly important due to the ever-increasing use of applications that allow multimedia transmission, such as virtual reality (VR), 3D videos, and internet of things (IoT) [1,2]. Looking back into various critical evolution junctions in the wireless communication domain, we find the inclusion of OFDM methodology as an important step towards enhancing the data rate transmission. OFDM has been widely used by many popular standards such as wireless local-area network (WLAN) (e.g., 802.11 a up to 802.11 ax) [5], digital audio broadcasting (DAB) [6], digital video broadcasting (DVB) [7], wireless wide area network (WWAN) (e.g., 802.16 m) [8], and long-term evolution (LTE) [9,10].
