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 paper recounts and revises the development of linear albegra system from ancient Chinese referenced on the acient Chinese text: The Nine Chapters on the Mathematical Art. The two main related ...

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 ...

Gold bilayered slit arrays with rectangular holes embedded into the metal surface are designed to enhance the circular dichroism (CD) effect of gold bilayered slit arrays. The rectangular holes in ...
