摘要
1 Introduction The fact that the spectrum resource is underutilised in certain bands has motivated the dynamic spectrum access(DSA)approach,which enables unlicensed secondary users(SUs)equipped with cognitive radio(CR)devices to access the spectrum without causing significant interference to primary users(PUs).Nowadays,the increasing bandwidth for wireless communication in millimetre-wave and Terahertz frequency bands puts higher requirements on the performance of spectrum sensing technique,the primary enabler of DSA.
