Quadrature Phase Shift Keying (QPSK) is a modulation technique which is widely used in wireless communication system due to its ability to transmit twice the data rate for a given bandwidth. This paper 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 (Spartan-3) using the Verilog Hardware Description Language (VHDL) on Xilinx ISE design suite 13.2.
