On the Outage and TIFR Capacity of Sensing Enhanced Spectrum Sharing Systems

The potential of improving the achievable throughput of spectrum sharing cognitive radio networks by enhancing them with spectrum sensing capabilities has recently lead to the introduction of a new spectrum access scheme called sensingbased spectrum sharing (SSS) or sensing-enhanced spectrum sharing (SESS). In this paper, the authors study the truncated channel inversion with fixed rate (TIFR) capacity and the outage capacity of a sensing-enhanced spectrum sharing (SESS) cognitive radio system for Rayleigh and Nakagami-m fading channels. They consider various constraints on the capacity, which include average transmit and interference power constraints, peak interference power constraints, and target detection probability constraints.
