In this paper the authors deal with the design & implementation of a verilog design of QPSK digital modulator based on the FPGA Quartus-II simulator. 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 counterpart. Digital modulation represents the transfer of the 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.
