Abstract :
A technique is described to approximate a linear time-invariant (LTI) system by a linear m-adic invariant (LMI) system or, equivalently, approximate a circulant matrix by a supercirculant matrix. This approximation reduces the number of multiplies required for computing cyclic convolution. Furtermore, the concepts of LMI systems are presented in a tutorial fashion. Examples are included to illustrate the efficacy of the approximation technique.
