A Study on Twin fold Power Identification Technique for Cognitive Radio Networks

Cognitive Radio CR is an innovative model for wireless communication that addresses the issue of spectrum inadequate utilization. Spectrum sensing is one of cognitive radios key tasks. Power identification is a popular spectrum sensing methodology due to its simplicity and lack of need for preexisting knowledge of the primary user PU . However, traditional energy detectors function poorly in low SNR regions. The CSS Cooperative Spectrum Sensing with double thresholds improved decision making validity, but resulted in some loss of sensing knowledge. In this study, we have projected a dual threshold Cooperative Spectrum Sensing approach where every CR Cognitive Radio communicates local resolution or perceived power to the FC Fusion Center based on the region where the perceived power is located. FC then renders an ultimate judgment based on local decisions and measured power values. Our simulation framework demonstrates that the suggested technique surpasses standard CSS in low SNR regions. The proposed method Twin fold Power Identification Technique for Cognitive Radio Networks TFPIT is better than conventional CSS methods in context of energy detection.
