On the energy detection performance based Welch's DCT algorithm in cognitive radio systems

Currently, modern devices and applications for communications need huge frequency bands since it has limited resources. To address this issue, the cognitive radio is considered a promised solution where its main function is exploiting the idle spectrum using one of spectrum sensing (SS) techniques....
