Paper Abstract

We present an improved phase generated carrier (PGC) demodulation method named PGC differential-self-multiplying-integrate (PGC-DSMI) algorithm in this paper. The performances of the new demodulation method are ameliorated via the elimination of the coefficients in the result of conventional PGC-differential-and-cross-multiplying (PGC-DCM) method. The advantages of the improved method are demonstrated theoretically and proved in the simulation. The results show that PGC-DSMI has a better linearity than PGC-DCM.
