Design of a Low Complexity and Fast Hardware Architecture for Digital Image Watermarking in FWHT Domain on FPGA

2014 Fifth International Symposium on Electronic System Design, 2014
This paper focuses on the design of an improved Discrete Fast Walsh Hadamard Transform (DFWHT) domain digital image watermarking algorithm and its low complexity as well as fast hardware architecture implementation on Xilinx based (version 14.7 Virtex-7 series) FPGA with target device xc7vx1140t-1flg1930, with maximum achieved frequency of 259.202 MHz.

A New Fast Discrete Curvelet Transform Spread OFDM Waveform based on FWHT FWHT Üzerine Kurulan Yeni Bir Hizli Ayrik Curvelet Dönüşümü Yayilmali OFDM Dalga Formu

2022
© 2022 IEEE.In this study, fast discrete Curvelet transform (FDCT) spread OFDM waveform (FWHT-FDCT-OFDM) based on fast Walsh Hadamard transform (FWHT) alternative to OFDM waveform is proposed for next generation wireless communication systems. The proposed waveform is a combination of FWHT and FDCT with OFDM waveform.
