SPS JSTSP Webinar: Distributed Signal Processing for Extremely Large-Scale Antenna Array Systems
Date: 30-July-2025
Time: 08:00 AM ET (New York Time)
Presenter(s): Dr. Tsung-Hui Chang & Dr. Yanqing Xu
About this topic:
Extremely large-scale antenna arrays (ELAA) play a critical role in enabling the functionalities of next generation wireless communication systems. However, as the number of antennas increases, ELAA systems face significant bottlenecks, such as excessive interconnection costs and high computational complexity. Efficient distributed signal processing (SP) algorithms show great promise in overcoming these challenges. In this talk, the presenters will provide a comprehensive overview of distributed SP algorithms for ELAA systems, tailored to address these bottlenecks. In particular, they focus on two representative forms of ELAA systems: single-base station ELAA systems and coordinated distributed antenna systems. For each form, they review the associated distributed SP algorithms in the literature. Additionally, they outline several important future research directions that are essential for improving the performance and practicality of ELAA systems.
