摘要: Abstract In this paper, the performance of spectrum sensing techniques over two wave diffused power (TWDP) fading channels has been investigated for CR based IoT devices. The ubiquitous objects on IoTs with cognitive capabilities are future that would enable intelligent decisions to achieve any time, place, interference-free and on-demand services. work, new closed-form expressions in terms Marcum-Q function Whittaker detection probability TWDP have derived different techniques. then used optimize decision threshold sensor nodes describing optimal behavior channels. error probabability Receiver Operating Characteristic (ROC) curves plotted operating point limiting values identified. loss traditional energy (ED), cyclostationary (CSD) matched filtering detector (MFD) analyzed. analytical results thus obtained validated through monte-carlo simulations.
