Design of Programmable Digital down Converter for Wimax

Design of a programmable digital down converter (DDC) has been proposed, which can be used in digital receivers that meets IEEE 802.16d/e (WiMAX) standard in wireless communication system. The design is based on the idea of software radio technology and the theorem of multi-rate signal processing, It can be implemented on FPGAs and can replace traditional ASICbased digital down converters in high channel count Software-Defined Radios.
