Abstract

In This paper, the bit error rate analysis (BER) and peak signal to noise ratio performance (PSNR) of discrete wavelet transform (DWT)-OFDM system is compared with conventional fast fourier transform (FFT)-OFDM system for colour image transmission, here we use different error correcting codes like Reed Solomon codes, low density parity check codes (LDPC). The transmitted colour image is found to have retrieved effectively under noisy and fading situations with implementation of sum-product algorithm like fast Fourier transforms, discrete wavelet transforms.
