Abstract

The article explores the feasibility of hardware implementation of complex high-speed digital filtering algorithms for voice channel in cell communication systems. For test case we use adaptive noise reduction
complex algorithm with embedded discrete fast Fourier transform and Wiener filtering functions.

Keywords: Wiener filtering, time domains, frequency domains, clock frequencies, double port RAM, finite state machine
