摘要

Cooperative spectrum sensing is the key technology that improves the detection performance by using the space diversity gain among cognitive users (CUs). However, it increases the energy consumption. In order to solve the problem of excessive energy consumption, we propose an energy-saving algorithm which can reduce redundant upload information by using the historical sensing results of CUs and the correlation between the sensing results of adjacent time slots. Energy consumption is further reduced by adding a prediction of the channel state. Meanwhile, the proposed algorithms can correct errors caused by the nonideal report channel and improve the detection performance of the system.
