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
The large beamforming gain used to operate at millimeter wave (mmWave) frequencies requires obtaining channel information to configure hybrid antenna arrays. Previously proposed wi…
Channel Tracking and Hybrid Precoding for Wideband Hybrid Millimeter Wave MIMO Systems
Javier Rodriguez-Fernandez, Nuria Gonzalez-Prelcic, Takayuki Shimizu
A major source of difficulty when operating with large arrays at mmWave frequencies is to estimate the wideband channel, since the use of hybrid architectures acts as a compression…
Hybrid precoding and combining for frequency-selective mmWave MIMO Systems with per-antenna power constraints
Javier Rodriguez-Fernandez, Roberto Lopez-Valcarce, Nuria Gonzalez-Prelcic
Configuring hybrid precoders and combiners is a major challenge to deploy practical mmWave communication systems. Prior work addresses the problem of designing hybrid precoders and…
