“…As highlighted earlier, most of the existing BF literature in the context of SatCom focuses on the BF design either at the space side or gateway side. However, the topic of adaptive BF at the terminal side has received limited attention [8,9,18,19]. The BF weights in many cases are the functions of the covariance matrices which are eventually the functions of the steering vectors in Line of Sight (LoS) channels.…”

“…In this context, the contribution in [18] studies a modular receive and transmit antenna terminal featuring digital BF at Ka-band frequencies within the framework of project Smart Antenna Terminal (SANTANA). The recent contribution in [19] provides an overview of aspects encountered during the design and realization of highly integrated antenna frontends dedicated to SatCom-on-the-move.…”

One of the promising solutions to address the spectrum scarcity problem in Satellite Communications (SatComs) is to exploit the use of non-exclusive Ka-band spectrum, which is primarily allocated to terrestrial Fixed Service (FS) microwave links. In this regard, this paper considers the spectral coexistence of FS links with the Fixed Satellite Services (FSS) system both in the downlink and the uplink. Out of several possible solutions to enable this coexistence, this paper deals with the terminal-side Sidelobe (SL) suppression and Beamforming (BF) techniques at the FSS terminal. Starting with a detailed review of existing SL suppression, BF techniques as well as Ka-band terminal status, first, we provide the detailed methodology on the employed raster scan based Direction of Arrival (DoA) estimation method. Subsequently, with the help of numerical results, we provide the performance evaluation of one SL suppression technique and one BF technique, considering a parabolic reflector with an array of auxiliary elements and the array of feeds, respectively. Finally, we discuss several interesting practical aspects to be considered while designing the proposed solutions.
