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…
Partial-Duplex Amplify-and-Forward Relaying: Spectral Efficiency Analysis under Self-Interference
Roberto López-Valcarce, Carlos Mosquera
We propose a novel mode of operation for Amplify-and-Forward relays in which the spectra of the relay input and output signals partially overlap. This partial-duplex relaying mode…
Distributed Precoding Systems in Multi-Gateway Multibeam Satellites: Regularization and Coarse Beamforming
Carlos Mosquera, Roberto Lopez-Valcarce, Vahid Joroughi
This paper deals with the problem of beamforming design in a multibeam satellite, which is shared by different groups of terminals -clusters-, each served by an Earth station or ga…
