TL;DR: This paper designs the sensing duration to maximize the achievable throughput for the secondary network under the constraint that the primary users are sufficiently protected, and forms the sensing-throughput tradeoff problem mathematically, and uses energy detection sensing scheme to prove that the formulated problem indeed has one optimal sensing time which yields the highest throughput.

TL;DR: This paper studies the fundamental tradeoff between sensing capability and achievable throughput of the secondary users and designs the design of sensing slot duration to maximize the achievable throughput for thesecondary users under the constraint that the primary users are sufficiently protected.

TL;DR: Spectrum sensing techniques from the optimal likelihood ratio test to energy detection, matched filtering detection, cyclostationary detection, eigenvalue-based sensing, joint space-time sensing, and robust sensing methods are reviewed.

TL;DR: A collision-throughput tradeoff problem is formulated which, based on the sensing time requirement and the traffic pattern of primary users, finds optimal value for the frame duration of CR operation so that the throughput of the CR network is maximized, yet the collision probability of the primary users is not greater than a threshold.

TL;DR: This work considers a point-to-multipoint cognitive radio network that shares a set of channels with a primary network and proposes two-phase mixed distributed/centralized control algorithms that require minimal cooperation between cognitive and primary devices.
