Design and Evaluation of a System-on-Chip based Modulator

Modulators are considered as the most vital block for any communication system. Different applications demand different modulation schemes with applications ranging from mobile communication, radar, radio stations, aerospace, covert communication and many more. In this paper, design of a System-on-Chip based Modulator on a Virtex-5 FPGA is proposed, which enables designers to program FPGA using high level language with nil or minimum knowledge of VHDL or Verilog programming. The proposed SoC based design is compared with reconfigurable modulator and CORDIC based modulator designs.
