A novel single carrier frequency domain equalizer based on discrete wavelet transform

Ali ÖZEN

A novel single carrier frequency domain channel equalizer (SC-FDE) based on discrete wavelet transform (SCDWT-FDE) has been proposed to improve the performance of conventional SC-FDE in this paper. Computer simulations have been performed to verify the performance of the proposed method in stationary and non-stationary frequency selective Rayleigh fading channels. The obtained simulation results using SC-FDE physical layer specifications have demonstrated that the proposed SC-DWT-FDE method has considerably better performance and carrier frequency offset (CFO) tracking than conventional SC-FDE ...Daha fazlası

A novel walsh hadamard based approach for ımproving performance of zero tail OFDM systems

Ali Özen

A novel zero tail OFDM (ZT OFDM) method based on Walsh Hadamard transform (ZT WHT OFDM) has been proposed to improve the performance of ZT OFDM systems, from 5G candidate waveforms in this paper. Computer simulations have been performed to show the performance of the proposed method in stationary and non-stationary frequency selective Rayleigh fading channels. The obtained simulation results using HIPERLAN/2 physical layer specifications have demonstrated that the proposed ZT WHT OFDM method has considerably better performance and Doppler shift tracking than conventional OFDM and ZT OFDM.
