Models, Methods and Waveforms for Estimation and Prediction of Doubly Sparse Time-Varying Channels
Wissal Benzine, Ali Bemani, Nassar Ksairi +1
This paper investigates channel estimation for linear time-varying (LTV) wireless channels under double sparsity, i.e., sparsity in both the delay and Doppler domains. An on-grid a…
