Sparse Channel Estimation for Massive MIMO-OFDM Systems Over Time-Varying Channels

IEEE Access, 2018
For downlink orthogonal frequency division multiplexing-based massive multiple-input-multiple-output transmission over the time-varying channel, channel estimation is very challenging due to numerous channel coefficients to be estimated.

Pilot-Efficient Channel Estimation for RIS-Aided Wireless Communication Systems: A Systematization

IEEE Open Journal of the Communications Society
Passive reconfigurable intelligent surfaces (RIS) can reshape the propagation environment with negligible radio-frequency power, yet they introduce a dominant channel-acquisition bottleneck, because the cascaded channel to be learned is high-dimensional ...
