Abstract

Spectrum sharing concepts have been widely employed in the design of practical systems with the aim to improve the utilization efficiency of the radio spectrum. Motivated by this, a comprehensive capacity study of spectrum sharing systems undergoing α-μ fading is performed in this paper. More specifically, assuming identical fading parameters, a closed-form expression for the delay-limited capacity is derived. In addition, based on the power allocation related to the outage capacity, a closed-form expression for the corresponding minimum outage probability is attained. Guidelines on how the ergodic capacity can be evaluated are also presented. Numerical plots are shown in order to investigate the effect of the fading parameters in the system capacity.
