In this paper the authors present the simulation results of digital modulation schemes BPSK and QPSK. Digital modulation is less complex, more secure and more efficient in long distance transmission. The noise detection and correction in digital is more efficient than analog. So it has more importance in modern communication system. These digital modulation schemes can be realized using FPGA (Field Programmable Gate Array). In this paper, BPSK and QPSK modulation techniques have been implemented on FPGA using VHSIC (Very High Speed Integrated Circuit) Hardware Description Language (VHDL) on Xilinx ISE 14.1 and simulated with MdelSim SE 6.0.
