On the Gaussian-Quadratic Rate-Distortion Function for Vector Sources with Individual Distortion Constraints
Shuao Chen, Junyuan Gao, Yuxuan Shi +4
This paper investigates the Gaussian-quadratic lossy compression with arbitrary source length under individual distortion constraints. The rate-distortion function (RDF) is lower-b…
A Modular O-RAN Testbed Based on SRS Open Source O-CU/O-DU and Massive Beams Modular O-RU
Fabian Göttsch, Oriol Font-Bach, Andreas Benzin +5
In this paper, we present a modular open radio access network (O-RAN) consisting of the 5G Core, a central (O-CU) and distributed unit (O-DU) by Software Radio Systems (SRS) and an…
Capacity-Region-Achieving Sparse Regression Codes for MIMO Multiple-Access Channels
Hao Yan, Lei Liu, Yuhao Liu +2
This paper proposes a coding framework for capacity-region-achieving sparse regression (SR) codes over MIMO multiple-access channels (MIMO-MAC), where a single SR code is used for…
Multi-view imaging in networked sensing systems: A covariance-based approach
Junyuan Gao, Weifeng Zhu, Yanmo Hu +5
This paper considers multi-view imaging in a sixth-generation (6G) integrated sensing and communication network, which consists of a transmit base-station (BS), multiple receive BS…
Artificial Magnetic Conductor Frame to Improve Impedance Matching and Radiation Symmetry in 22 Array for 6G Applications
Edoardo Giusti, Krishan Kumar Tiwari, C. J. Reddy +3
An Artificial Magnetic Conductor (AMC) frame capable of improving the impedance matching of a 22 array for 6G applications without degrading isolation performance is presen…
FDD CSI Feedback under Finite Downlink Training: A Rate-Distortion Perspective
Shuao Chen, Junyuan Gao, Yuxuan Shi +4
This paper establishes the theoretical limits of channel state information (CSI) feedback in frequency-division duplexing (FDD) multi-antenna orthogonal frequency-division multiple…
