Abstract
In this paper, a comparison studying of different 4G digital modulation techniques over AWGN channel, as well as Rayleigh and Rician fading channels were performed. Firstly, we investigated QPSK, DQPSK, 16-QAM and 64-QAM modulated signal constellations, and then we generated BER and SNR data for analysing different communication systems. At last, we used MATLAB SIMULINK to perform Monte Carlo simulate for 16-QAM system.
