Cyclostationary and energy detection spectrum sensing beyond 5G waveforms
Electronic Research Archive, 2023 The cyclostationary spectrum (CS) method is one of the best at what it does because it effectively detects idle spectrum with low signal-to-noise ratios (SNR).

Energy Detection Based Carrier Sense in LPWAN
IEEE Access, 2023 Extensive research has been conducted on imperfect carrier sense based on energy detection; however, the effect of the finite packet length, finite carrier sense period, and arbitrary start time of the carrier sense for the arrived signal on the result ...

Energy, information, detection, and action [PDF]
Behavioral and Brain Sciences, 2001 Before one can talk about global arrays and multimodal detection, one must be clear about the concept of information: How is it different from energy and how is it detected? And can it come to specify a needed movement? We consider these issues in our commentary.

An Energy Detection-Based Spectrum-Sensing Method for Cognitive Radio
Wireless Communications and Mobile Computing, 2022 Energy detection (ED) method is one of the most commonly used signal-sensing methods in spectrum sensing due to its low implementation complexity. ED can achieve good detection performance when the noise variance is known.
