There are sources to reach uniform linear array with elements.
First consider the signals and impinging on an array with elements and.
Consider a 16-element array with elements uniformly spaced on the line of distance equal to half wavelength.
As shown in Figure 1, consider an L-element array with elements uniformly spaced on the line of distance equal to d.
Then, if it is used for finding SVs of an -by-1 or 1-by array with elements representing samples of a signal, it will return only one singular value that is not enough to express the whole signal.
In this work, we consider a multihop wireless network that consists of a finite set of nodes where each node is stationary and has a MIMO antenna array with elements or DOFs for each node to transmit and receive signals.
Let us consider a two dimensional plot (array with elements F ( i 1, i 2 ) ) with horizontal numbering related to the i 2 index and vertical numbering related to the i 1 index; [ F ( 1, 1 ) F ( 1, 2 ) ⋯ F ( 1, N 2 ) F ( 2, 1 ) F ( 2, 2 ) ⋯ F ( 2, N 2 ) ⋮ ⋱ ⋮ F ( N 1, 1 ) F ( N 1, 2 ) ⋯ F ( N 1, N 2 ) ].
In the simulations, three arrays with element number M=10, 15, 20 are used; their mainbeam width are about 24°, 16°, and 12°, respectively (calculated by conventional beamformer with weight vector equals to the steering vector of desired signal).

The MAT file contains a cell array with 79 elements, where each element corresponds to a study ID number.
