FDD massive MIMO downlink channel estimation with complex hybrid generalized approximate message passing algorithm

Precise channel state information (CSI) is essential for the massive multiple-input multiple-output (MIMO) system to achieve high spectrum and energy efficiency performance in the forthcoming 5G communication. Combined with angular domain channel sparsity, compressive sensing (CS) technique is intro...
