Performance Analysis of Dwt- Ofdm and Fft-ofdm Systems
AbstractPerformance of Orthogonal Frequency Division Multiplexing (OFDM) systems using Fast Fourier Transforms (FFT) and Discrete Wavelet Transform (DWT) are analyzed in this paper. The performance of DWT-OFDM is assessed by various parameters such as BER, eye diagram and constellation diagram. BER is the ratio of the no. of bits with error to the total no. of bits transmitted through the chann...
متن کاملSimulation of Models and BER Performances of DWT-OFDM versus FFT-OFDM
Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier modulation system. The transmission channel is divided into a number of subchannel in which each subchannel is assigned a subcarrier. Conventional OFDM systems use IFFT and FFT algorithms at the transmitter and receiver respectively to multiplex the signals and transmit them simultaneously over a number of subcarriers. The syst...
متن کاملPerformance Analysis of Hash Encrypted DWT-OFDM and Hash Encrypted FFT-OFDM Systems
Abstract— Orthogonal Frequency Division Multiplexing (OFDM), in the recent past is being preferably used in wireless communication because of its high data rate and its unique property of the transmitted symbols being mathematically orthogonal. This mathematical orthogonality allows signals with different frequencies to propagate in the same subcarrier unlike traditional Frequency Division Mult...
متن کاملPerformance Analysis of OFDM System under FFT, DWT and DCT Based Transform Techniques
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 envi...
