Digital Post-Distortion for Joint Mitigation of Transmitter I/Q Imbalance and Power Amplifier Nonlinearities in Multiuser MIMO Networks

In this paper, we propose a novel digital post-distortion (DPoD) technique designed to improve the received signal quality in orthogonal frequency-division multiple (OFDM)-based multi-user multiple-input multiple-output (MU-MIMO) systems suffering from severe coexisting transmitter impairments in the form of power ampl...

Designing Multi‑Reality Futures: Speculative Explorations of Seamless and Meaningful XR Experiences

As XR technologies continuously evolve, research has increasingly examined XR systems that integrate multiple forms of reality. This has given rise to the concept of "multi‑reality", an experience that span user interactions across the Reality-Virtuality (RV) continuum: reality, augmented reality (AR), augmented virtua...
