FDD Downlink Channel Estimation Solution With Common Sparsity Learning Algorithm and Zero-Partition Enhanced GAMP Algorithm

To acquire precise channel state information in the forthcoming 5G frequency division duplexing (FDD) communication system, we study the virtual angular domain channel common sparsity in the massive multiple-input multiple-output orthogonal frequency division multiplexing downlink transmission syste...
