Optimal Cyclic Convolution System for Maximizing SNR

Abstract

The problem of maximizing SNR at the output of a cyclic convolution system is considered. It is shown that the required impulse response function of the system has an interpretation analogous to that of matched filter. Similarities and differences with the matched filter are discussed.
