An Efficient Multiplexing Technique For 5G Wireless Network: Analysis and Selection

Abstract

 The 5G cellular communication technology is intended to base on the present Long-Term
Evolution (LTE) 4G networks with adopted features. Features of low power consumption and the
constant power level should be the major requirement for an efficient channel allocation method. In this
research work, an analysis was performed on multiplexing techniques: Orthogonal Frequency Division
Multiplexing (OFDM), Generalized Frequency Division Multiplexing (GFDM), Universal Filtered
Multicarrier (UFMC) and Filter-Bank Multicarrier (FBMC). Smooth power level had been analyzed
according to Power Spectral Density (PSD) function vs normalized frequency using AWGN channel
model. The simulation was done by MATLAB 2019 Simulink software for OFDM and GFDM that were
further compared to existing results of UFMC and FBMC multiplexing techniques. Calculated power for
OFDM and GFDM were 32.1mW and 40.23 µW respectively. Comparative results showed the better
smooth power spectrum, micro-watt power consumption and better hardware configuration for GFDM.
That’s why GFDM channel allocation method selection is one step ahead for the next generation
multiplexing technique
