| Abstract(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 H_0), the studied frequency band is occupied only by a PU (hypothesis H_1), the studied frequency band is occupied only by another SU (hypothesis H_2) and the studied frequency band is occupied by PU and another SU simultaneously (hypothesis H_3).Most of the related works have considered the binary hypothesis testing problem (H_0 and H_1).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. |
