This paper formulates and studies a novel algorithm for federated learning from large collections of local datasets. This algorithm capitalizes on an intrinsic network structure that relates the local datasets via an undirected "empirical" graph. We

An iterative calibration method of 5G mmW vector- sum phase shifter (VSPS) is presented in this paper. The phase and amplitude imbalances of I and Q branches can be tuned. The phase is adjusted with a tunable polyphase filter (PPF) by changing its re

Moving to sub-THz frequencies introduces new challenges for wireless communications systems in terms of design, implementation, and testing. This paper presents a measurement technique for over-the-air (OTA) characterisation of sub-THz antennas at WR

As relative bandwidth increases, beam squint, i.e., frequency dependent directivity, limits the wideband performance of phase-shifter steered arrays. This effect is already notable in 5G systems operating at 28 GHz and above with 400/800 MHz bandwidt

We consider a multi-source relaying system where independent sources randomly generate status update packets which are sent to the destination with the aid of a relay through unreliable links. We develop transmission scheduling policies to minimize t

The sixth generation (6G) communications is expected to involve the use of the sub-Terahertz. Electromagnetic waves in this band is vulnerable to blockages by physical obstacles, besides the severe limitation of coverage area compared to in conventio

We develop online scheduling policies to minimize the sum average age of information (AoI) subject to transmission capacity and long-run average resource constraints in a multisource two-hop system, where independent sources randomly generate status
