| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper tackles the four-level hypothesis problem for spectrum sharing between primary users (PUs) and secondary users (SUs). The considered hypotheses are as follows; the studied frequency band is vacant (hypothesis H0), the studied frequency band is occupied only by a PU (hypothesis H1), the studied frequency band is occupied only by another SU (hypothesis H2) and the studied frequency band is occupied by PU and another SU simultaneously (hypothesis H3).Most of the related works have considered the binary hypothesis testing problem (H0 and H1).To enable four-level hypothesis testing, in our previous work we used cyclostationary based spectrum sensing with intentional frequency shift in the SU signal. We found the minimum frequency shift that leads to a required level of detection performance. However, random carrier frequency offset due to a mismatch between oscillators has not been considered even though it may deteriorate the detection performance significantly in practical systems. Therefore, we propose a robust cyclostationary spectrum sensing technique. In addition, in the multiple hypothesis problem, setting design parameters to satisfy constraints is difficult. Therefore, we propose a method to set proper design parameters. Numerical result verify the proposed parameter setting method. | |
