In this paper, a 2D DOA estimator in arbitrary array geometry for massive MIMO has been analyzed and modeled based on low-complexity 2D Fourier domain
line search MUSIC algorithm.

The resulting completed (detruncated) sinogram (being optimized in the Fourier domain
) is reconstructed using any reconstruction algorithm that can be applied on nontruncated projection data, for example, the standard FBP framework.
If we set [mathematical expression not reproducible], from the traditional Poisson sum formula for g(t) in the Fourier domain
, that is, (1), we obtain
Rotation in the spatial domain causes rotation of the Fourier domain
by the same angle .
In our study Fourier domain
(Optovue, RTVue, version 22.214.171.124) type of Optical Coherence Tomography machine was used to calculate Macular thickness.

H calculates grayscale intensity modified in Fourier domain
, E, using Fourier transform values applied over luminance and each of two chrominance channels.
Currently, two main types of OCT systems can be considered: Time-Domain OCT (TD-OCT) and Fourier Domain
OCT (FD-OCT)--that can be further divided in Spectral Domain OCT (SD-OCT) and Swept Source OCT (SS-OCT) as we will see [1,4].
