Direction-of-Arrival Estimation of Closely Spaced Emitters Using Compact Arrays
Hoi-Shun Lui,Hon Tat Hui +1 more
TL;DR: In this paper, the performance of the matrix pencil method (MPM) that applies to DOA estimations is investigated through Monte Carlo simulations, and the results show that closely spaced emitters can be accurately resolved using linear compact array with an array aperture as small as around half wavelength.

Super-Wideband Massive MIMO
TL;DR: This work turns mutual coupling (MC) from a foe to a friend of MIMO systems design, thereby challenging a basic percept in antenna systems engineering that promotes MC mitigation/compensation and derives analytically the asymptotically optimum spacing-to-antenna-size ratio.

The Design of an Ultrawideband T-Pulse With a Linear Phase Fitting the FCC Mask
TL;DR: In this article, a discrete finite time domain pulse is designed under the constraint of the Federal Communications Commission (FCC) ultrawideband (UWB) spectral mask, which enjoys the advantage of having a linear phase over the frequency band of interest and is orthogonal to its shifted version of one or more baud time.
