Abstract

In this article hardware implementation of Sequency ordered Complex Hadamard Transform (SCHT) on FPGA is presented. SCHT is quite similar to Discrete Fourier Transform (DFT) but it consumes less computational time. DFT is replaceable by SCHT in several applications such as Communication, Spectrum analysis and estimation, Signal processing and image watermarking. The 8-point radix-2 fast SCHT is evaluated on FPGA to minimize its computational time, besides that certain parameters of fast SCHT matrices are analysed. Finally SCHT hardware implemented results and MATLAB simulated results are compared at the cost of time to verify the effectiveness of the SCHT on FPGA.
