OFDM (Orthogonal Frequency Division Multiplexing) transmissions are arising as important modulation techniques because of its robustness against interference. Various modulation schemes have been used to implement OFDM. In this paper, the OFDM transceiver system is implemented using MATLAB. Gaussian Minimum Shift Keying modulation technique has been implemented in the proposed OFDM. The bit error rate (BER) performance has been evaluated in AWGN (Additive White Gaussian Noise) channel and is compared to Quadrature Phase Shift Keying modulation scheme. General Terms Bit error rate, Matlab, Additive White Gaussian Noise.
