    Abstract :

    Massive capacity, everywhere coverage and highest energy efficiency is requirement of next generation cellular networks. In order to meet these targets, device to device communication is being considered for future heterogeneous networks. In this paper we are going to improve spectral efficiency by improving bit error rate (BER) using qudrature amplitude modulation technique. We shall present BER for 16-QAM, 64-QAM, and 256-QAM in Gaussian noise channel and under flat Rayleigh fading conditions.
