Rethinking Fronthaul Topologies for Cell-Free 6G Networks
Max Franke, Arash Pourdamghani, Fabian Göttsch +2
Due to significant progress in physical layer (PHY) technologies, future 6G networks are expected to feature much denser antenna deployments. Cell-free MIMO network designs are one…
Towards Standardizing OTFS: A Candidate Waveform for Next-Generation Wireless Networks
Mingcheng Nie, Ruoxi Chong, Shuangyang Li +5
The standardization of the sixth-generation (6G) has recently commenced to address the rapidly growing demands for enhanced wireless network services. Nevertheless, existing wirele…
Optimizing Fronthaul Quantization for Flexible User Load in Cell-Free Massive MIMO
Fabian Göttsch, Max Franke, Arash Pourdamghani +2
We investigate the physical layer (PHY) spectral efficiency and fronthaul network load of a scalable user-centric cell-free massive MIMO system. Each user-centric cluster processor…
A Comparison among Single Carrier, OFDM, and OTFS in mmWave Multi-Connectivity Downlink Transmissions
Fabian Göttsch, Shuangyang Li, Lorenzo Miretti +2
In this paper, we perform a comparative study of common wireless communication waveforms, namely the single carrier (SC), orthogonal frequency-division multiplexing (OFDM), and ort…
