SVD-Assisted FI Sparse Bayesian Learning for OTFS Channel Estimation
The sparse Bayesian learning (SBL) is an efficient channel estimation approach for orthogonal time-frequency-space (OTFS) systems. However, the ability of SBL to identify nonzero elements is limited by the sensing model structure, and its computational efficiency is limited by the computationally intensive covariance m...
