Abstract

Abstract:
Due to the increasing complexity in modern communication systems, State of the art
data communication systems make extensive use of digital hardware. Besides baseband
digital processing, the frequency tuning function is now being shifted from analog to
digital implementation where the integration, cost, and case of programming are the
primary motivations.
In this paper, a proposed technique for implementation of Digital Up Converter (DUC)
and Digital Down Converter (DDC) is presented. The objectives are achieving an
optimized and cost effective hardware implementation. The diverse hardware
requirements for these systems including processing speed, flexibility, integration and
time-to-market necessitate an FPGA based implementation platform.
