An Efficient WOLA Structured OQAM-FBMC Transceiver

Abstract

In this paper, we evaluate and analyze performance of these systems with windowed overlap-add (WOLA) technique. The offset quadrature amplitude modulation - filter bank basis multi carrier (OQAM-FBMC) has been attracted. OQAM-FBMC was nominated as one of new waveforms for 5G communications due to its capability of frequency selectivity, cyclic prefix (CP) and robustness to carrier frequency offset (CFO). In spite of these advantages, many researchers have claimed pros and cons for the usage of FBMC, among those the excessive computational complexity is considered as a major hurdle to deploy for direct employment. We analyze the bit error rate (BER) performance through computer simulation to verify the validity of the proposed method.
