Charanjit Singh · Indian Journal of Science and Technology · 2009
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. Keywords: CIC Filter, digital down converter, half band filter, software defined radio, WiMAX.
