Efficiency improvement using adaptive hybrid modulation/coding/frequency selection scheme for future 5G wireless network

This paper presents an approach of a Matlab/Simulink-based model for Hybrid M-QAM/L-FSK (4/16 HQFM) modulation scheme with a non-coherent detection of 4-ary FSK demodulator in the presence of Additive White Gaussian Noise (AWGN) channel which maintains the same theoretical results of Bit Error Rate (BER), Power Spectral Density (PSD) and bandwidth efficiency in previous literature using Monte Carlo simulation without using the Phase Acquisition Algorithm (PAA). A new Adaptive modulation with coding and carrier frequency selection scheme (Adaptive Hybrid MCFS) will be proposed and applied for different types of cells to be adapted to channel conditions for improving the achievable data rates and spectral efficiency of the overall system which is recommended for 5G cellular network and can be easily implemented using the Software Defined Radio (SDR) systems.
