“…For instance, authors in [30] evaluated the bit error ratio (BER) performance of different signal mapping techniques (i.e., QPSK, 16-PSK, and 16-QAM) for an OFDM-based image transmission system over the AWGN channel. Similarly, authors in [25] analyzed the BER performance for another set of signal mapping schemes (i.e., BPSK, QPSK, 16-PSK, and 256-PSK). In [31], authors have implemented an OFDM-based image transmission system on software-defined radios (SDR) and compared the BER performance in the case of different signal mapping schemes (i.e, BPSK, QPSK, 16-PSK, and 256-PSK).…”

“…The transmitter of mMIMO-OFDM is the same as that of conventional OFDM except that pre-coding and re-ordering of all users are carried out in the frequency domain before performing the inverse fast Fourier transform (IFFT). On the other hand, the receiver side of mMIMO-OFDM is similar to that of conventional OFDM [25]. In this work, the performance of mMIMO-OFDM systems based on FFT, DWT, and FrFT is evaluated by sending and receiving the reference baboon image under different SNR values, modulation orders, and a varying number of end-users.…”

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.
