Abstract
In this paper, we investigates the effects of two different modulation schemes for image transmission using an OFDM (Orthogonal Frequency Division Multiplexing) transceiver. The main aim is to evaluate the performance between 16PSK (Phase Shift Keying) and 16QAM (Quadrature amplitude modulation) in context of BER (Bit Error Rate) in AWGN (Additive White Gaussian Noise) channel. We evaluate the performance of these modulation schemes using MATLAB simulations. The results show that QAM is a better modulation scheme than PSK for the image transfer using OFDM transceiver. The data modulated by PSK modulation technique gets more affected by the channel effects and more number of errors occur, as compared to QAM.
