Abstract—This project presents the simulation results of digital modulation schemes BASK,BPSK and BFSK. 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. Digital modulation represents the transfer of digital bit stream from the transmitter to the receiver via the analog channels. During the modulation process the information signal modifies one or more carrier parameters leading to shift keying techniques. So it has more importance in modern communication systems. These digital modulation schemes can be realized using FPGA (Field Programmable Gate Array). This method employs the advantages of reliability, concurrent operation and low cost .It uses minimum number of blocks necessary for achieving BASK,BPSK and BFSK modulation. In this project BASK,BPSK and BFSK modulation techniques have been implemented on FPGA using Verilog Hardware Description Language on Xilinx ISE 10.1 and simulated with Modelsim SE 6.5.
