In this paper,we have investigated 4-level hypothesis based spectrum sensing technique for spectrum spectrum sharing between primary users (PUs) and secondary users (SUs).
In the most of related works, they focused on 2-level hypothesis, H0: frequency is vacant and H1: frequency is used by PU.
In the 4-level hypothesis, we add two hypothesis, H2: frequency is used by SU and H3: frequency is used by PU and SU.
Benefit of the 4-level hypothesis approach is that it is possible to achieve more effective spectrum utilization by recognizing details of status of frequency.
In a previous work of spectrum sensing for the 4-level hypothesis, cyclostationarity of SU is designed to enable accurate recognition.
Specifically, a small frequency shift is added to the SU signal.
However, in this approach, frequency offset caused by Doppler shift and uncertainty of local oscillator is a significant issue for accurate spectrum sensing in the 4-level hypothesis.
For this issue, we proposed a test statistic which can achieve robustness against the frequency offset and introduced a design method of the proposed spectrum sensing.
The numerical results have shown the validity of the design and a robustness of the proposed spectrum sensing. |
