Full-Duplex Cognitive Radio With Asynchronous Energy-Efficient Sensing.

Using a novel embedded Markov chain, we model and analyze a cognitive radio performing full-duplex spectrum sensing which is being carried out imperfectly-i.e., with errors-and asynchronously with primary traffic, from the perspective of energy efficiency. The effect of sensing frequency, which is varied by inserting sleeping periods between sensing processes is investigated, with focus on: 1) the...
