This paper focuses on analyzing the effects of primary user (PU) signal arrival in sensing intervals on the local spectrum sensing performance. Firstly, we investigate the energy detector performance when the probability of an arrival of the PU signal is uniformly distributed. Thus, the global detection performance is degraded in comparison with the conventional case in which two null hypotheses are considered. In the second step, in order to cope with this degradation, we propose an approach to the time of arrival (ToA) estimator at each single cognitive radio (CR) to reduce the noise-only portion in the received signal at each CR ; thus, detection performance at the fusion center (FC) is increased. The theoretical analysis and numerical simulation are validate that the proposed approach results in the higher performance than the conventional detection scheme.
