Level of Regions for Deformed Braid Arrangements
Yanru Chen, Houshan Fu, Suijie Wang +1
This paper primarily investigates a specific type of deformation of the braid arrangement in , denoted by and defined in (1.2). Let…
Level Decompositions for Symmetric Deformations of the Braid Arrangement
Yanru Chen, Suijie Wang, Jinxing Yang +1
Let be finite and nonempty, and let be the associated sequence of symmetric deformations of t…
Two Bijections on NBC Subsets
Houshan Fu, Baoren Peng, Suijie Wang +1
We establish two explicit bijections: from acyclic reorientations of an oriented matroid to no broken circuit (NBC) subsets of its underlying matroid, and from regions of a real hy…
Low-complexity Beam Selection algorithms based on SVD for MmWave Massive MIMO Systems
Jinxing Yang, Jihong Yu, Shuai Wang +1
To realize mmWave massive MIMO systems in practice, Beamspace MIMO with beam selection provides an attractive solution at a considerably reduced number of radio frequency (RF) chai…
