Walsh - Hadamard Transformation of a Convolution

Abstract

A convolution is mathematical operation used in signal processing,in the homomorphous signal processing and digital image processing(e.g. image interpolation). In regard of computational complexity ofthe convolution in the time domain, it used to calculate in the otherdomain. Exp. x(n) * h(n) R X(W) × H(W), resp. X(W) × H(W),shows that a convolution in the time domain corresponds tomultiplication in the Z domain, respectively frequency domain. Thispaper shows utilization of Walsh-Hadamard orthogonal transformationsfor convolution.
