摘要: An energy harvesting cognitive radio scenario is considered where a secondary user (SU) with finite battery capacity opportunistically accesses the primary (PU) channels. The objective to maximize throughput of SU under neutrality constraint and fading channel conditions in single-user multi-channel setting. A selection criterion based on probabilistic availability SU, conditions, network's belief state proposed, which chooses best subset channels for sensing, yielding higher throughput. We construct channel-aware optimal myopic sensing strategies Partially Observable Markov Decision Process framework proposed criterion. effects errors collisions between PU latter are studied. It shown that there exists trade-off transmission duration lost collisions.
