Design and Implementation of Effective QPSK Modulator Based on FPGA

Abstract: The objective of this project is to develop an implementable effective QPSK modulator that uses less power for operation. The design of QPSK modulator has be done using Matlab/Simulink and Xilinx System Generator. The modulator algorithm has been implemented on FPGA(Spartan3) using the Verilog Hardware Description Language on Xilinx ISE Design suite 13.2. Then the final designed and simulated results are applied for real time such as Satellite Communication, Video Conferencing etc.

Keywords: Matlab/Simulink, Xilinx, System generator, FPGA, Spartan3.
