Channel Estimation for Hybrid MIMO Systems With Array Model Errors and Beam Squint Effects
Kabuto Arai, Koji Ishibashi
This paper proposes a channel estimation method for hybrid wideband multiple-input-multiple-output (MIMO) systems in high-frequency bands, including millimeter-wave (mmWave) and su…
Creative Agents: Simulating the Systems Model of Creativity with Generative Agents
Naomi Imasato, Kazuki Miyazawa, Takayuki Nagai +1
With the growing popularity of generative AI for images, video, and music, we witnessed models rapidly improve in quality and performance. However, not much attention is paid towar…
The Fefferman Metric for Twistor CR Manifolds and Conformal Geodesics in Dimension Three
Taiji Marugame
We give an explicit description of the Fefferman metric for twistor CR manifolds in terms of Riemannian structures on the base conformal 3-manifolds. As an application, we prove th…
Quantum geometric tensor determines the pure-state i.i.d. conversion rate in the resource theory of asymmetry for any compact Lie group
Koji Yamaguchi, Yosuke Mitsuhashi, Tomohiro Shitara +1
Quantifying physical concepts in terms of the ultimate performance of a given task has been central to theoretical progress, as illustrated by thermodynamic entropy and entanglemen…
