This paper proposes a new paradigm for spectrum sharing between cellular wireless communications (CWC) and radio astronomy systems (RAS). In contrast to the existing paradigm of geographical and spectral isolation between CWC and RAS, this paper develops a three phase spectrum access, which enables geographical and spectral coexistence between CWC and RAS. Shared spectrum access zone (SSAZ) is created around the RAS site and CWC cells within the SSAZ follow the three phase spectrum access…

This paper defines—through detailed simulations based on standard International Telecommunications Union channel and antenna models—scenarios in which active users may introduce harmful interference to passive sensing, and reviews a number of promising techniques that can enable active/passive sharing above 100 GHz.
A New Paradigm for Non-Geostationary Satellite Communications and Radio Astronomy System
TLDR
This paper proposes a new paradigm to accommodate the rapid growth of non-geostationary orbit (NGSO) satellite communications system (SCS) and radio astronomy system (RAS) and addresses two related problems of the new paradigm, namely the spectrum resource allocation problem and the RAS data transport problem.
Impacts of Large-Scale NGSO Satellites: RFI and A New Paradigm for Satellite Communications and Radio Astronomy Systems
TLDR
A new paradigm where SCS and RAS are integrated into the NGSO satellite system is proposed, thus effectively creating large-scale telescopes in orbit and illustrating the advantages of the proposed paradigm in terms of accessible spectrum bands, RAS observation performance, and SCS maximum mean supportable data rate as well as enabling coexistence and growths of both types of services.

TLDR
A new signal model is developed at the output of RAS array processing when the LNA at each RAS receiver behaves nonlinearly and the capability of the proposed methods to keep the squared error almost as low as that of a linear system.
Beyond 5G: Big Data Processing for Better Spectrum Utilization
TLDR
It is shown that the 6G network significantly benefits from effective dynamic spectrum management (DSM) based on RSMs that provide rich and accurate knowledge of the radio context, a knowledge that is stored and processed within database-oriented subsystems designed to support wireless networks for improving spectral efficiency.
