In the last year, I’ve learnt how spatial frequencies are the basic building blocks of wireless channels. Near- and far-field channels use them in different ways to represent planar and spherical waves. Alva, Özlem, Nikolaos, and I have written a tutorial paper explaining these concepts and their implications. It is a recommend reading for anyone who wants to understand MIMO channels better.
There has been a great hope that near-field communications would bring a new dimension to exploit, characterized by their signature beamfocusing feature. However, is it just a hope or is it grounded in reality? Find the answer in our latest paper 👇 https://lnkd.in/eBkwxtC7 Co-Authors: Özlem Tuğfe Demir, Nikolaos Kolomvakis, and Emil Björnson.

Excellent tutorial, Emil Björnson and all. Thanks for sharing.
