RECONSTRUCTION OF DISCRETE FINITE LENGTH SIGNAL FROM ITS END POINT AND FOURIER TRANSFORM MAGNITUDE

【摘要】 <正> Signal reconstruction from its Fourier Transform (FT) magnitude is one of the researcher’s focuses in signal processing areas and is often encountered into a variety of physical and engineering problems. Generally, a signal cannot be uniquely specified only from its FT magnitude unless there is some additional information, e.g. it is already known that the signal is the minimum or maximum phase, its FT sign information is available and partial sample points of the signal are given.更多还原
