摘要：
We considered the problem of use the reliability of unlicensed users for cooperative spectrum sensing in cognitive radio systems by analyzing the Huffman encoding algorithm. We present a novel cooperative spectrum sensing algorithm in cognitive radio systems. We drive the close-form expressions for the average sending bits for each unlicensed user for cooperation and expression for the probability of the detection and the false-alarm for the novel cooperative spectrum sensing scheme. Finally, we show through numerical results the potential cooperative spectrum sensing performance improvement with using the reliability of unlicensed users.
