Spectrum database for coexistence of terrestrial FS and FSS satellite systems in the 17.7-19.7 GHz band

Abstract

In this article we develop a database-based spectrum access for the Ka band, allowing fixed satellite services (FSS) receivers to coexist with the terrestrial fixed services (FS) system, thus increasing the downlink capacity of the satellite system. The main focus of this paper is to study FS interference to FSS user terminal receivers in the 17.7-19.7 GHz band as the interference from FSS to FS stations has been found to be minimal. We analyse the FS spectrum use in Finland using the information from the national FS registry, which adds novelty to our approach but, more importantly, makes our analysis realistic and in line with practical systems. The main results regarding spatial distribution,
used link distances, transmission powers, antenna heights, and bandwidths are given. This provides a clear view on spectrum sharing possibilities in the band. Obtained information is used in designing secondary use, assuming the FSS system has access to the band at the locations, frequencies, and times where interference-free operation is possible. Coexistence simulations using the ITU-R path loss model P.452-15 and the database design taking into account practical parameters and findings from the FS registry analysis show that the FSS system could clearly increase its capacity.
