dc.description.abstractA novel frequency domain channel equalizer, inspired by [1], based on discrete wavelet transform (DWT) based OFDM has been proposed to improve the frequency domain channel equalizer employed OFDM systems in this paper. In this study, the performance of DWT based OFDM frequency domain channel equalizer (DWT-OFDM-FDE) has been compared with the conventional FFT based OFDM (FFT-OFDM-FDE) systems. Computer simulations have been performed to verify the performance of the proposed method in frequency selective Rayleigh fading channels. The obtained simulation results using HIPERLAN/2 standard have demonstrated that the proposed DWT-OFDM-FDE system has considerably better performance than the conventional FFT-OFDM-FDE system in all modulation types and also provides high SNR improvement of approximately 8 dB for a BER value of 1E-3. © 2016 IEEE.
