IRS-Enhanced Energy Detection for Spectrum Sensing in Cognitive Radio Networks

Energy detection is of crucial importance in cognitive radio networks. However, its performance is poor when the channel fading is severe, which causes interference to the primary users. In order to tackle this issue, an intelligent reflecting surface (IRS)-enhanced energy detection for spectrum sen...
