Space–bandwidth-efficient realizations of linear systems

Not Accessible

Your library or personal account may give you access

Abstract

One can obtain either exact realizations or useful approximations of linear systems or matrix–vector products that arise in many different applications by implementing them in the form of multistage or multichannel fractional Fourier-domain filters, resulting in space–bandwidth-efficient systems with acceptable decreases in accuracy. Varying the number and the configuration of filters enables one to trade off between accuracy and efficiency in a flexible manner. The proposed scheme constitutes a systematic way of exploiting the regularity or structure of a given linear system or matrix, even when that structure is not readily apparent.
