Abstract

M-ary Quadrature Amplitude Modulation (M-QAM) is an important technique for modulation of digital signals in wireless communication system. Due to the increasing demands for high rate data outputs in wireless communications, it is essential to investigate methods of achieving high spectral efficiency which would take into account the wireless channel models. The bit error rate (BER) is a parameter which gives an excellent indication of the performance of a data link such as radio or optic fiber system. Understanding the method of evaluating the BER will aid in the design of a more suitable modulation scheme that will best suit the channel quality, thus delivering the optimum and efficient data rate to the downlink terminal. This paper will focus on evaluation of BERs for M-QAM modulation varying from 4 to 64 and for integer values of bit energy-to-noise power spectral density ratio (Eb/No) between 0 and 7 using Matlab R2013a simulation tool in AWGN channel.
