IWindowFT

Inverse Window Fourier Transform

Calling Sequence

sig = IWindowFT(specgm,w,Name)

Parameters

Inputs:

specgm :

Window Fourier Transform of sig, complex matrix

w :

window half-length used to construct specgm

Name :

string: 'Rectangle', 'Hanning', 'Hamming', 'Gaussian', 'Blackman' name of window used to construct specgm

Outputs:

sig :

1-d signal

Description

supposes signal is non-periodic, i.e. zero-padded reconstruction is not exact in the border region, but it is exact in the center
