Spectrum-Sharing Transmission Capacity
This paper analyzes spectrum sharing between multiple systems. The efficiency of spectrum sharing is determined primarily by interference, which is a function of the spatial densities of the transmitters in systems dependent on the chosen spectrum sharing method. One method is underlay, which allows all systems to concurrently use the whole spectrum, and the other is overlay, in which a system only utilizes its own assigned spectrum. The authors define the Spectrum-sharing Transmission Capacity (S-TC) as the number of successful transmissions per unit area subject to outage probability constraints for each system.
