Multilinear Singular Value Decomposition for Millimeter Wave Channel Parameter Estimation

Abstract: Fifth generation (5G) cellular standards are set to utilize millimeter wave (mmWave) frequencies, which enable data speeds greater than 10 Gbps and sub-centimeter localization accuracy. These capabilities rely on accurate estimates of the channel parameters, which we define as the angle of arrival, angle of departure, and path distance for each path between the transmitter and receiver. Estimating the channel parameters in a computationally efficient manner poses a challenge because it requires estimation of p… Show more

“…However, this reshaping does not account for the multidimensional grid structure inherent in the data [9] . The joint use of tensor modeling and CS techniques for channel estimation in massive MIMO systems has been addressed recently [2,16]. Alternatively, tensor decomposition-based subspace methods are proposed in [5,25].…”

“…Standard 5G mmWave channel estimation is based on either compressive sensing approaches [18], which express the sparsity in an appropriate domain, or on tensor decompositions, where the dominant higher-order singular values can be related to the dominant signal paths [19], [20]. A joint tensor decomposition and compressed sensing based multidimensional channel parameter estimation method is proposed in [21]. However, these methods do not account for the intra-cluster spread of angles or delay.…”

“…However, for each dimension, one dimensional search is required and the complexity of the spectral search may still be unacceptably high for real-time problems. In [32], a multilinear singular value decomposition (MSVD) method is used for channel parameter estimation. The Tucker form of the MSVD enables paths to be extracted based on signal energy.…”
