Abstract: The development of mobile Internet and Internet of things (IoT), the 5th generation (5G) wireless communications will foresee explosive increase in mobile traffic. To address challenges in 5 Gisuchias higher spectral efficiency, imassive connectivity, and low rilatency, some Non-Orthogonal Multiplei Accessi (NOMA) is chemesihaveibeenirecentlyiactivelyiinvestigatediincludingipower-domainiNOMA,imultipleiaccess with Low-Density Spreading (LDS), Sparse Code Multiple Access (SCMA), Multi-user Shared Access (MUSA), pattern division multiple access (PDMA). Pattern Division Multiple Access is the key technique for analyzing group of users at a time. In this paper we investigate BER performance for 5G systems with different multiple accesses schemes, i.e Orthogonal Frequency Division Multiplexing (OFDM), Filter Bank Multicarrier (FBMC), Generalized Frequency Division Multiplexing (GFDM),in comparison to these we design a closed form analysis method of Multi-user FDMC technique far better. Simulation results show that MU FDMC performs better than conventional methods.
