Time-modulated phased array controlled with nonideal bipolar squared periodic sequences
R. Maneiro-Catoira, J. Brégains, José A. García-Naya +1
Bipolar (+/-1) sequences with no zero state suit particularly well for safeguarding the switched feeding network efficiency when applied to time-modulated arrays (TMAs). During the…
Time-modulated multibeam phased arrays with periodic Nyquist pulses
R. Maneiro-Catoira, J. Brégains, José A. García-Naya +1
We present a single sideband time-modulated multibeam phased array governed by periodic Nyquist pulsed signals. A Nyquist pulse is a physically realizable approach to the ideal sin…
Time-modulated arrays with Haar wavelets
R. Maneiro-Catoira, J. Brégains, José A. García-Naya +1
Time-modulated arrays (TMAs) can effectively perform beamsteering over the first positive harmonic pattern by applying progressively delayed versions of stair-step approximations o…
Analog beamforming using time-modulated arrays with digitally preprocessed rectangular sequences
R. Maneiro-Catoira, J. Brégains, José A. García-Naya +1
Conventional time-modulated arrays are based on the application of variable-width periodical rectangular pulses (easily implemented with radio frequency switches) to the individual…
Time-modulated array beamforming with periodic stair-step pulses
R. Maneiro-Catoira, J. Brégains, José A. García-Naya +1
Time-modulated arrays (TMAs) are able to improve the side-lobe level of the radiation pattern at the fundamental mode but cannot steer the beam at such a mode towards a given direc…
Bit error probability and capacity bound of OFDM systems in deterministic doubly-selective channels
Tomás Domínguez-Bolaño, José Rodríguez-Piñeiro, José A. García-Naya +1
Doubly-selective channels, such as those that occur when the transmitter and the receiver move relative to each other at high speeds, are a key scenario for fifth generation (5G) c…
