Modulators Using Verilog

This project presents the simulation results of digital modulation schemes BASK,BPSK and BFSK. In long distance transmission digital communication is more efficient and secure. In digital communication part noise detection and correction is very simple than analog communication. Digital modulation represents the transfer of digital bit stream from the transmitter to the receiver via the analog channels in an easy way. During the modulation the information signal modifies one or more carrier signal parameters leading to shift keying techniques. So it has more importance in modern communication systems. These three digital modulation schemes can be implemented using FPGA (Field Programmable Gate Array). This project employs the advantages of reliability, concurrent operation and minimum cost .It uses minimum number of blocks necessary for achieving BASK,BPSK and BFSK modulation techniques. 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.
