不仅研究了无线通信系统中的多路效应，还研究了不同位置的次用户对于感知主

Not only the multi-path effect in the wireless communication system is studied, but also the difference in the perception of the primary user signal by the secondary users at different locations. Finally, the fusion of the perception information through data fusion improves the perception performance.

Not only the multiple-way effect in wireless communication system, but also the difference between the sub-users in different locations to perceive the main user signal, and finally the information of perception is fused by data fusion, which improves the perceptive performance.

This paper not only studies the multi-channel effect in wireless communication system, but also studies the difference of the secondary users' perception of the main user signal in different locations. Finally, the sensing information is fused by data fusion, which improves the sensing performance.<br>
