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…
Learning Power Spectrum Maps from Quantized Power Measurements
Daniel Romero, Seung-Jun Kim, Georgios B. Giannakis +1
Power spectral density (PSD) maps providing the distribution of RF power across space and frequency are constructed using power measurements collected by a network of low-cost sens…
