Popis:	Traditional phase generation carrier (PGC) demodulation algorithm is often affected by modulation depth C and carrier phase delay θ. An improved PGC demodulation method was put forward in this article. The results show that when in different modulation depth, the demodulation result was stable and almost identical to the original signal to be test. With different phase delay values, such as θ=30°and 60°, the signal amplitude demodulated by the improved algorithm was consistent with the original signal. The new demodulation method can make the accuracy of the phase generation carrier technology better and improve the system performance.
