Transceiver Design For Downlink NOMA - FBMC

Abstract

Fifth generation (5G) cellular communication technique guarantees spectral efficiency, low latency, high data rates with throughput and massive connectivity. NOMA is better other OMA techniques like OFDMA etc. NOMA is divided into mainly two types i.e., Power domain NOMA and Code based NOMA. In the first phase we discussed downlink power domain NOMA for multiuser environment. System Capacity and behaviour of multiuser NOMA systems are analyzed in AWGN channel model. Accurate power allocation in multiuser case is crucial job. A power allocation strategy in multiuser NOMA system on the basis of distances with different UEs from base station (BS)is implemented . We also proposed phase shift phenomena to further enhance the system performance with capacity. Interference between users’ signals is reduced by assigning with different phase shifts at the time of modulation. Also, we implement a basic model of FBMC and analyze its BER performance. In the second phase of research the existing two and three users NOMA are analyzed under NYUSIM channel models. We proposed a model for NOMA-FBMC for two and three user environment and analyzed its performance under AWGN and NYUSIM Channel models.
