Abstract: This article presents a novel constellation modeling method for fast and accurate calibration of beamforming integrated circuits (BFICs) and radio frequency (RF) chains in large-scale phased ...

Abstract: Coprime arrays achieve a larger virtual array aperture with the same number of physical elements through their difference co-array. However, the improvement in degrees of freedom (DOF) is ...

The proposed high-precision fast direction-of-arrival estimation method for planar array includes two steps, and the expression of the result includes two items: 1) a 2-stage grid search approach over ...

One of Groovy‘s most significant “goodies” is the ability to intercept calls, even to standard Java classes, and either override existing methods or even add new methods dynamically. In this blog post ...
