Analysis of Cognitive Radio Spectrum Sensing Techniques over Nakagami-m Fading Channel

Abstract

As the demand of wireless communication increases exponentially, with the same ratio scarcity of spectrum also originates. To overcome this spectrum scarcity a novel approach, Cognitive Radio (CR) shows development of an opportunistic and promising technology. This paper explores implementation and analysis of the CR spectrum sensing techniques such as Matched filtering, Energy detection and Cyclostationary feature detection on MATLAB platform by simulation. We analyze performance of these techniques over, Nakagami-m fading channel with AWGN channel for both the BPSK and QPSK modulation.

“…Examples include Dear Tomorrow (2020) -("a global climate storytelling project where people write climate messages to loved ones living in the future"); or engaging people in the process of creating speculative fiction within creative and participatory methodological parameters (e.g. Doyle, 2020;Haraway, 2016;Rousell et al, 2017). 6 A striking recent methodological example is the "Counter-Factual Worlds Generator".…”
