Channel Estimation and Hybrid Precoding for Frequency Selective Multiuser mmWave MIMO Systems
J. P. González-Coma, J. Rodríguez-Fernández, N. González-Prelcic +2
Configuring the hybrid precoders and combiners in a millimeter wave (mmWave) multiuser (MU) multiple-input multiple-output (MIMO) system is challenging in frequency selective chann…
Broadband Synchronization and Compressive Channel Estimation for Hybrid mmWave MIMO Systems
Javier Rodriguez-Fernandez
Synchronization is a fundamental procedure in cellular systems whereby an UE acquires the time and frequency information required to decode the data transmitted by a BS. Due to the…
Dictionary Learning for Channel Estimation in Hybrid Frequency-Selective mmWave MIMO Systems
Hongxiang Xie, Javier Rodríguez-Fernández, Nuria González-Prelcic
Exploiting channel sparsity at millimeter wave (mmWave) frequencies reduces the high training overhead associated with the channel estimation stage. Compressive sensing (CS) channe…
Joint Synchronization, Phase Noise and Compressive Channel Estimation in Hybrid Frequency-Selective mmWave MIMO Systems
Javier Rodriguez-Fernandez, Nuria Gonzalez-Prelcic
