Decoupling and Matching Strategies for Compact Antenna Arrays
F. Estevão S. Pereira, Josef A. Nossek, F. Rodrigo P. Cavalcanti
Antenna arrays have been used in various applications and have become an important tool to achieve high spectral efficiency in wireless communications. Its use brings to the commun…
On Reciprocity in Physically Consistent TDD Systems with Coupled Antennas
Tobias Laas, Josef A. Nossek, Samer Bazzi +1
We consider the reciprocity of the information-theoretic channel of Time Division Duplex (TDD) Multi-User-Multiple Input Multiple Output (MU-MIMO) systems in the up- and downlink.…
5G Downlink Multi-Beam Signal Design for LOS Positioning
Anastasios Kakkavas, Gonzalo Seco-Granados, Henk Wymeersch +3
In this work, we study optimal transmit strategies for minimizing the positioning error bound in a line-of-sight scenario, under different levels of prior knowledge of the channel…
