Abstract :
Convincing amelioration have been reported by many authors of Wavelet-based signal processing association by utilizing a pair of Wavelet transforms, where the Wavelets form a Hilbert transform pair. This paper propose a novel VLSI design methodology of multiplier-less architecture for single level 1-D Hilbert transform pair using Biorthogonal Wavelets which efficiently implements the 1-D Discrete Wavelet Transform (DWT) without multipliers thereby reducing the resource to a great extent which effectively abate the hardware cost. The design has been validated by implementing it on a Xilinx 14.1 version based FPGA using Virtex device. VHDL has been used as the hardware description language and the simulation has been accomplished on ISIM simulator. The VLSI architecture also implements resource (adders or subtractors) sharing to further reduce the computational complexity. The multiplication has been performed through partial sum generation and finally adding them through the use of 4:2 and 3:2 compressors and Vector Merging Adders (VMA) and the results shows improvement than [1].
