Abstract: The paper represents performance evaluation of Bit Error Rate (BER) for conventional (DFT) and wavelet (DWT) based orthogonal frequency division multiplexing (OFDM) with various modulation techniques. There are different modulation schemes such as Binary Phase Shit Keying (BPSK) and Quadrature Phase Shift Keying (QPSK). The performance in between these modulation techniques is evaluated and analyzed to obtain lowest possible Bit Error Rate (BER) to be transmitted. Simulation is performed on the software named MATLAB.
Keywords: Bit Error Rate, Discrete Fourier transform, Discrete Wavelet Transform, Orthogonal frequency division multiplexing.
