Tensor-Based Orthogonal Matching Pursuit with Phase Rotation for Channel Estimation In Hybrid Beamforming Mimo-Ofdm Systems
ICASSP 2022accepted
Tensor decomposition is often employed for channel estimation in hybrid beamforming MIMO-OFDM systems because of multiple dimensions and channel sparsity. We propose to incorporate phase rotation in factor matrices of tensor-based orthogonal matching pursuit (T-OMP) algorithm to solve the energy lea…
