| Abstract | In this chapter, the authors introduced a new sensing technique called the advanced-two-phase detector's spectrum sensing technique. The proposed technique is divided into two phases. The first is an energy detector with a single adaptive threshold and the second has two adaptive thresholds. In the proposed model, if the energy detector with a single adaptive threshold does not detect the primary user signal then the energy detector with two adaptive thresholds tries to detect the primary user signal and gives the appropriate decision. The authors used MATLAB® software for simulation, and graphical results confirm that the proposed advanced two-phase detector technique improves the detection performance and outperforms the energy detector and the cyclo detector-2010, adaptive spectrum sensing-2012, energy detection technique for adaptive spectrum sensing-2015, and energy detector and energy-detector advanced two-phase detector-2015 by 34.4%, 33.9%, 13.4%, and 2.9% at −a 10 dB signal-to-noise ratio, respectively. Further, in terms of sensing time, the presented scheme yields a smaller sensing time frame than the energy detector and the cyclo detector-2010, adaptive spectrum sensing-2012, Adaptive sensing technique using energy detector (EDT-ASS)-2015, and the energy detector and the Energy Detector with Adaptive Threshold (ED-ADT) detector-2015 scheme in the order of 6.8, 2.6, 0.6, and 1.8 ms at −20 dB signal-to-noise, respectively.This chapter proposes Energy Detection (ED) and Energy Detector with Adaptive Threshold (ED-ADT) sensing techniques, where the proposed system model consists of two detectors. The first stage uses a single threshold energy detector, and the second stage uses ED-ADT scheme. The ED and ED-ADT detection schemes focused on the problem of failure over sensing. The proposed advanced-two-phase detectors (TPD) scheme is a modern version of ED and ED-ADT detector-2015 and gives better results. Advanced wireless networks deal with bandwidth crisis problems by minimizing the sensing failure problem. This scheme reduces the error rate and sensing time and also enhances detection performance. Simulation results confirm that the proposed advanced-TPD scheme outperforms other existing schemes at a low Signal to Noise Ratio. This scheme produces a lower detection time than the ED and cyclo detector-2010, adaptive spectrum sensing-2012, EDT-ASS-2015, and ED and ED-ADT detector-2015 schemes in the order of 6.8, 2.6, 0.6, and 1.8 ms at -20 dB SNR, respectively. |
