Abstract
Cognitive radio (CR) offers solution to the problem of spectrum underutilization by opportunistic spectrum access. Spectrum sensing is one of the important functions of CR as it affects both Primary Users (PUs) protection and Secondary Users (SUs) achievable throughput. In this paper, we are introducing a spectrum sensing scheme which selects either single threshold or double threshold energy detection method based on the estimated Signal to Noise Ratio (SNR) value of the channel. This scheme achieves a better tradeoff between sensing performance and achievable throughput as compared to conventional methods that works purely on single threshold or double threshold energy detection method.
