Codebook-Based User Tracking in IRS-Assisted mmWave Communication Networks

Moritz Garkisch, Vahid Jamali, Robert Schober

ICASSP 2023accepted

In this paper, we present a novel mobile user tracking (UT) scheme for codebook-based intelligent reflecting surface (IRS)-aided millimeter wave (mmWave) systems. The proposed UT scheme exploits the temporal correlation of the direction from the IRS to the mobile user for selecting IRS phase shifts…

A Single-RF Architecture for Multiuser Massive MIMO Via Reflecting Surfaces

Ali Bereyhi, Vahid Jamali, Ralf R. Müller, Antonia M. Tulino, Georg Fischer, Robert Schober

ICASSP 2020accepted

In this work, we propose a new single-RF MIMO architecture which enjoys high scalability and energy-efficiency. The transmitter in this proposal consists of a single RF illuminator radiating towards a reflecting surface. Each element on the reflecting surface re-transmits its received signal after a…
