“…In the last decade, tensor modeling has been employed in a variety of signal processing problems [24]- [29], in particular to solve wireless communications related problems such as semi-blind receivers for MIMO systems [30], [31], channel estimation methods for cooperative communications [32], [33], direction of arrival estimation and beamforming in array processing [34]- [36], and, more recently, compressed channel estimation in massive MIMO systems [37], [38]. This paper links tensor modeling to IRS-based MIMO systems, and shows that exploiting the tensor structure of the received signals provides an effective way to solve the channel estimation problem.…”

“…Remark For the one‐dimensional DOA estimation algorithm based on tensor, the construction method of the tensor estimation model based on the Hank matrix and the construction method of the tensor estimation model using the spatial smoothing idea are essentially the same [15, 16]. The former is mainly used here to facilitate readers' understanding.…”

“…However, the newly emerged tensor-based DOA estimation algorithm is favoured by many scholars because of its ability to efficiently process high-dimensional data, strong denoising ability, and being applicable to single snapshot and multiple snapshots [14][15][16][17]. Ref.…”

“…Moreover, due to its inherent requirements for data sparsity, the number of estimable targets is less under a certain number of elements [13]. However, the newly emerged tensorbased DOA estimation algorithm is favored by many scholars because of its ability to efficiently process high-dimensional data, strong denoising ability, and being applicable to single snapshot and multiple snapshots [14,15,16,17,18,19,20]. Under certain conditions such as SNR and number of snapshots, this kind of algorithm can decompose the approximately pure steering vector matrix as the factor matrix of the estimation tensor model by using the low rank characteristics and internal structure of the received signal data, and then obtain the DOA information of the target by using the rotation invariance characteristics of Vandermonde matrix or other subspace-based DOA estimation algorithms.…”
