Title
Impact of Imperfect Spectrum Sensing on Hybrid Backscatter Assisted Cognitive Wireless Powered Radio Networks
Abstract
In this paper, we propose a proper sensing period when the detection probability of determining the state of the primary user (PU) changes in a hybrid harvest-then-transmit (HTT) system according to the sensing period. The proposed system uses cooperative spectrum sensing based on energy detection using “ n-out-of-K” voting rule to the existing hybrid HTT system. The performance of the proposed hybrid HTT system is evaluated numerically. The numerical results show that there exists the optimal sensing period and our proposed hybrid HTT system can achieve the ideal throughput even for imperfect sensing situations.
