The Resolution of the Gibbs Phenomenon for Fractional Fourier Series
The nth partial sums of a classical Fourier series have large oscillations near the jump discontinuities. This behavior is the well-known Gibbs phenomenon. Recently, the inverse polynomial reconstruction method (IPRM) has been successfully implemented to reconstruct piecewise smooth functions by reducing the effects of the Gibbs phenomenon for Fourier series. This paper addresses that the similar phenomenon will be observed in fractional Fourier series (FrFS) expansion, and expects that the existed IPRM for resolution of the Gibbs phenomenon for FrFS appears to be the same as for Fourier series. Two numerical examples are investigated. The result indicates that the IPRM method completely eliminates Gibbs phenomenon and gives exact reconstruction results.
