Capacity of FBMC/OQAM Transceiver System with SRRC Filter and Intrinsic Interference for 5G Wireless Communication System

Abstract

Filter Bank Multicarrier with Offset Quadrature Amplitude Modulation (FBMC/OQAM) has become the most widely adopted technology in next generation wireless communication system(5G). Moreover, The FBMC/OQAM system supports high data rate, low impulse noise and high bandwidth efficiency. In this paper, capacity of FBMC/OQAM transceiver system using square root raised cosine filter (SRRC) pulse shaping is analyzed through information theoretic. The FBMC systems adopt proper pulse shaping with good time and frequency localization properties to avoid interference and maintain orthogonally in the real field among subcarriers. Moreover, our analytical model is further extended in order to gain insight into the effect of the intrinsic interference in the performance of our system. Furthermore, the spectral efficiency of FBMC/OQAM system is analyzed when the effect of Intersymbol Interference (ISI) and Inter-Carrier Interference (ICI) is considered
