Performance analysis of a hybrid OFDM-MIMO multiresonator system: synchronization, CFO estimation, and return loss evaluation

Abstract

The ever-evolving landscape of wireless communication technologies demands innovative solutions to address synchronization challenges, carrier frequency offset (CFO) issues, and impedance mismatches. In this context, our research focuses on advancing the field through the development of a hybrid orthogonal frequency-division multiplexingmultiple-input, multiple-output (OFDM-MIMO) multiresonator system. Recent studies in wireless communication technologies have underscored the critical importance of addressing synchronization errors, CFO-induced interference, and impedance mismatches in communication systems [14]. The advent of OFDM and MIMO techniques has significantly enhanced data transmission capabilities [59]. However, the complexities arising from CFO and synchronization discrepancies can compromise the overall performance of such systems [1014].
