Prior Frequency Band Allocation for Spectrum Sharing based on Interference Distribution
Bounpasith Chaleunsouk, Koichi Adachi (UEC) RCS2021-111
Abstract (in Japanese) (See Japanese page) 
(in English) Spectrum sharing allows multiple users, i.e., a primary user (PU) to a secondary user (SU), to share the same frequency band while protecting the communication quality of PU temporally and spatially.In the conventional spectrum sharing, SU has to temporarily stop the sharing to determine the presence or
absence of PU communication at the moving destination. Therefore, it is difficult for SU to use frequency continuously.In conventional research, an algorithm was proposed to detect vacant frequency in advance using the received signal strength information stored in the spectrum database (SD). However, the conventional research does not consider the shadowing error, which is between the information stored in the SD and the practical information, and the fluctuation of fading. Thus, SU may use the frequency with a high probability to interfere with the PU. Hence, in this study, we propose an algorithm that detects vacant frequencies using SD and allocates frequencies based on the modeled interference distribution in advance. Simulation result shows that the proposed method can reduce the probability of interference from SU to PU by more than 90% compared to the conventional method.
