Time-Varying Channel Estimation Based on Distributed Compressed Sensing for OFDM Systems

For orthogonal frequency division multiplexing (OFDM) systems in high-mobility scenarios, the estimation of time-varying multipath channels not only has a large error, which affects system performance, but also requires plenty of pilots, resulting in low spectral efficiency. To address these issues,...
