QPSK, a modulation mode with a high frequency band utilization ratio and a strong anti-noise immunity,is widely used in the field of military and satellite communication. This article based on the analysis of the traditional QPSK signal modulation and demodulation mechanism, proposes an improved QPSK signal modulation and demodulation algorithm, and have a further in-depth analysis of the feasibility of this algorithm. Finally, by MATLAB software simulation testing, simulation results shows that the algorithm can accurately generate a QPSK signal and complete a rapidly demodulation of a QPSK signal.
