Open publisher page 0 citations

Abstract

A modulation/demodulation experiment platform based FPGA is presented summarily.This experiment platformhas a core of EP3C25Q240C8 FPGA,and some common modulation/demodulation modes can be finished in it.The design process of FSK modulation/demodulation system is presented in detail with QUARTUS II,and the result of softwaresimulation and actual output signal is presented.And the realization of ASK and DPSK modulation/demodulation system is presented briefly.Results indicate that the experiment platform has a good practical ability and strong operability.
