Channel estimation of multi-user millimeter wave massive MIMO system based on random grid tensor decomposition
By using the sparse scattering characteristics of the millimeter wave channel and the spatial structure of the tensor, a channel estimation method based on random grid tensor decomposition was proposed. The received signal was represented as a fourth-order tensor and the user channel was decoupled b...
