Scalable Distortion-Aware Clustering for Fronthaul-Limited Cell-Free MIMO Networks
Zehua Li, Raviraj Adve, Israfil Bahceci +1
This paper studies distortion-aware clustering for uplink fronthaul-limited cell-free MIMO networks employing maximum ratio combining (MRC). While MRC is appealing for its low-comp…
Remote Interference Mitigation through Null Precoding and Fractional Programming
Xuyang Sun, Hussein A. Ammar, Israfil Bahceci +3
With the rapid deployment of 5G systems, remote interference (RI) caused by atmospheric ducting has emerged as an occasional, but critical challenge. This phenomenon occurs when th…
Handoff Design in User-Centric Cell-Free Massive MIMO Networks Using DRL
Hussein A. Ammar, Raviraj Adve, Shahram Shahbazpanahi +2
In the user-centric cell-free massive MIMO (UC-mMIMO) network scheme, user mobility necessitates updating the set of serving access points to maintain the user-centric clustering.…
Channel Estimation with Asynchronous Reception for User-Centric Cell-Free MIMO Systems
Xuyang Sun, Hussein A. Ammar, Raviraj Adve +2
The user-centric, cell-free wireless network is a promising next-generation communication system, but signal synchronization issues arise due to distributed access points and lack…
