Abstract: Linear sparse arrays (coprime and nested arrays) have been studied extensively as a means of performing direction of arrival (DoA) estimation while bypassing Nyquist sampling theorem.

Abstract: In this paper, a low complexity channel estimation method is proposed for two-dimensional (2-D) massive MIMO systems with uniform rectangular arrays of antennas. Instead of assuming ...

In this note we illustrate and develop further with mathematics and examples, the work on successive standardization (or normalization) that is studied earlier by the same authors in [1] and [2]. Thus ...

The circular sector patch antenna is studied in C-band (4 GHz - 8 GHz). In this paper, we present steps of designing the circular sector antenna then a comparison with a rectangular antenna in ...

College of Physics & Electronic Engineering, Xianyang Normal University, Xianyang, China. Chirality, including spiral, propeller, and polymolecular chirality, is a ...

My lab is using multielectrode arrays to record from the retina. These arrays (Litke arrays from UC Santa Cruz) are either rectangular (1x2 mm; 60 um pitch) or hexagonal (30um or 120 um pitch). The ...
