Open publisher page 0 citations

Abstract

As a basic modulation technique,PSK is widely used in the communication system.This Paper introduces a design method about the phase-shift keying to modulate the baseband signal.To make the system more flexibly,we utilize the DDS technique to get carrier wave whose frequency and phase areadjustable.In addition,We use the DSP Builder software made by ALTERA Company to improve ourdesign's efficiency.
