Modern signal processing problems are often solved in the digital domain due to the availability of powerful VLSI circuits which allow to perform complex operations in real-time, without the well-known shortcomings of analog implementations. Interpolation filters are integral part of a modern communication transmitter. This paper presents the design and FPGA implementation for a digital up converter or interpolation filter for a WiMAX communication system. Multistage implementation approach has been used to reduce the hardware requirement. The results have been presented for an xc3sd1800a-4fg676 FPGA device.
