Dealing with Interference in Distributed Large-scale MIMO Systems: A Statistical Approach [PDF]

open access: yes, 2014
This paper considers the problem of interference control through the use of second-order statistics in massive MIMO multi-cell networks. We consider both the cases of co-located massive arrays and large-scale distributed antenna settings.

Nonreciprocal Yagi–Uda Filtering Antennas

open access: yesIEEE Antennas and Wireless Propagation Letters, 2019
This paper proposes a novel and compact nonreciprocal filtering antenna based on temporal modulation. The device is composed of a third order filtering section integrated into a Yagi-Uda planar printed antenna. Strong nonreciprocity in transmission and reception is achieved at the same operation frequency by time-modulating the resonators of the ...
