Recently, substantial attention has been paid to improve the spectral efficiency of communication setups using different spectrum sharing techniques. This paper aims to study the capacity of fading spectrum sharing channels in the case where there is no channel state information available at the transmitters and receivers. The channel capacity bounds are obtained under secondary user input power, different primary user received interference power and also primary user peak and average signal-to-interference-and-noise (SINR) constraints. Simulation results show that there is considerable potential for data transmission of unlicensed users even with no fading channels state information.
