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

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. To track this problem, this paper proposes a novel sparse chan...
