A comparison of optimization techniques for power patterns with low sidelobes generated by linear arrays with efficient excitation distributions
(John Wiley & Sons, Inc., 2005-04-05)
[Abstract] Equispaced linear arrays that have uniformly excited central elements and monotonically decreasing flanking segments have been shown to yield low-sidelobe patterns with specified constraints on the effective ...
On the feasibility of time-modulated arrays for digital linear modulations: a theoretical analysis
(Institute of Electrical and Electronics Engineers, 2014)
[Abstract] Wireless communications are widely based on linear digital modulation methods, which introduce the digital baseband information in the amplitude and/or in the phase of a carrier sinusoid. Time-modulated arrays, ...
Wideband Hybrid Precoding Using Time Modulated Arrays
(Institute of Electrical and Electronics Engineers, 2020-08-05)
[Abstract] Hybrid digital-analog precoding is a cost effective solution for transmitting over the large bandwidths and huge antenna arrays available in the millimeter wave frequency bands. In this work we focus on the ...
