Discrete Time

Fourier Transform (DTFT) has been tremendously used to study cyclical behaviors in a wide range of fields (Alam et al.

Relationship between Quaternion

Fourier Transform Infrared Spectrometry, Wiley, New York, 1986.

In this paper, we propose a method for resolving overlapping signals based on

Fourier transform and inverse

Fourier transform.

(3) A novel ambiguity resolution based on integer search and inverse

Fourier transform is developed for fixed UCAs, and hence, it is applicable to real-time AOA estimations.

The special affine

Fourier transform (SAFT) [3, 4], also known as the offset linear canonical transform [5, 6] or the inhomogeneous canonical transform [5], is a six-parameter (a, b, c, d, [u.sub.0], [w.sub.0]) class of linear integral transform.

In [7], the author studied that the fractional

Fourier transform (FrFT) can be reduced to the classical

Fourier transform.

Fourier Transform. This is an integral transform that transforms a function of one or more variables (in spatial domain) to another function (in frequency domain) of the same number of variables [3, 13, 14].

The main idea now consists in a combination of the discrete Laplace and a nonequispaced

Fourier transform [6, 11, 12, 18, 19, 23, 27].

An improved method called Window

Fourier Transform (WFT) (Lei et al., 2010) is put up by Gbaor.

The main problem here is to determine which properties of f guarantees the p-summability of its periodic

Fourier transform. In this topic, chronologically one should apparently start with the celebrated paper by S.N.
