VLSI Based FPGA Design of Digital Modulation Schemes BASK and BPSK

Miss. Neha P. Shrirao and Prof. A. P. Thakare


Modulation is the process of facilitating the transfer of information over a medium. Digital modulation is less complex, more secure and more efficient in long distance transmission. The noise detection and correction is more efficient in digital modulation than analog. So it has more importance in modern communication system. 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. These shift keying techniques are Amplitude shift keying (ASK), Phase shift keying (PSK) and Frequency shift keying (FSK). All of these techniques vary a parameter of a sinusoid to represent the information which we wish to send. A sinusoid has three different parameters that can be varied. These are its amplitude, phase and frequency. These digital modulation techniques can be realized using FPGA (Field-programmable gate-array). Software-Defined Radio (SDR) transmitter employs the minimum number of blocks necessary for achieving BASK and BPSK modulation. The modulating and carrier signals can be user controlled and the modulators are developed and compiled to a Verilog Hardware Description Language (VHDL) net list. The functionality of these digital modulators are demonstrated through simulations using the Model Sim software and synthesis using Quartus-II software.
