A Review On Handover Mechanisms For Future Generation Wireless Networks

Abstract

With Increasing Number Of Users And Multimedia Applications, Bandwidth Efficiency In Cellular Networks Has Become A Critical Aspect For System Design. Bandwidth Is A Vital Resource Shared By Wireless Networks. Hence Its In Critical To Enhance Bandwidth Efficiency. Orthogonal Frequency Division Multiplexing (OFDM) And Non-Orthogonal Multiple Access (NOMA) Have Been The Leading Contenders For Modern Wireless Networks. NOMA Is A Technique In Which Multiple Users Data Is Separated In The Power Domain. A Typical Cellular System Generally Has The Capability Of Automatic Fallback Or Handover. In Such Cases, There Can Be A Switching From One Of The Technologies To Another Parallel Or Co-existing Technology In Case Of Changes In System Parameters Such As Bit Error Rate (BER) Etc.Multi User Detection Or MUD Is A Serious Challenge Faced In The Field Of Wireless And Cellular Communications. Due To The High Spectral Efficiency, Non-orthogonal Multiple Access (NOMA) Based Systems Are Becoming The Latest Choice For 5G Networks And Onwards. This Paper Presents A Review On Co-existence Of NOMA And OFDM Systems For Future Generation Wireless Networks.
