FPGA implementation of digital modulation techniques

This paper presents the review of the different digital modulation techniques and the various methods and tools that are used to implement it on FPGA along with the design summary and logic utilization of the resources. It includes an approach for the implementation of three modulators mainly Amplitude Shift Keying modulator, Phase Shift Keying modulators and Frequency Shift Keying modulator in VHDL by means of Xilinx 13.1 and simulation in Modelsim. The same modulators has also been developed in MATLAB/SIMULINK environment. The various factors that affect the choice of a particular modulation technique have also been discussed and accordingly anyone of the techniques can be adopted taking into consideration the application.
