چکیده
Peak Signal-to-Noise Ratio (PSNR) is a serious issue in OFDM systems. Several techniques have been proposed by researchers to maintain PSNR. In this paper, the Peak Signal-to-Noise Ratio (PSNR) performance of conventional Fast Fourier Transform (FFT)-OFDM system and discrete cosine transform (DCT)-OFDM system is compared with discrete wavelet transform (DWT)-OFDM system in a Gaussian Noise environment along with error correcting codes like Reed Solomon, LDPC. Also we compare all techniques on the basis of other simulation parameters like WPSNR, MSE, SSIM CORR2. KeywordsDCT, DWT, OFDM, Reed Solomon, LDPC.

متن کاملBit Error Rate Reduction of Dwt Based Ofdm Systems
--In OFDM systems, Fast Fourier transform (FFT) is used for frequency translation, and recently Discrete Wavelet Transform (DWT) has replaced FFT for frequency translation. 16-QAM (Quadrature amplitude modulation) scheme has been used in the OFDM system for both DWT and FFT based models. This work presents a modified OFDM system that is based on a low complexity interleaving process which is ap...
