An Overview for Channel Equalization Techniques in Filter Bank

Filter Bank Multi-Carrier Offset-QAM (FBMC OQAM) is one of the hottest topics of research in 5G multicarrier methodologies. As a result of its high spectral efficiency, too- low sidelobe leakage, zero cyclic prefix (CP), and multiphase filter design, the receiver's channel equalization is the most important task toward achieving a high data rate and reliable wireless communication. However, different types of impairments, such as fading, Doppler shifts, and Inter Symbol Interference (ISI), are inflicted on the transmitted data symbols as they travel through the wireless channel, lowering the quality of the network as a whole. Numerous channel equalization algorithms have been proposed for use in communication systems to help alleviate the negative effects of the channel. In this paper, we provide a survey of equalization methods used by the receiver of a wireless FBMC OQAM communication system. Every approach's central idea, architecture, and operation are detailed.
