In this work, we provide performance analysis and comparison for three different cognitive radio (CR) strategies, namely, interwave, underlay, and overlay in a scenario with a primary communication in the presence of a secondary one. We investigate the three different spectrum sharing techniques in terms of theoretical limits represented by capacity achievable by the cognitive user, assuming power constraints and additive white Gaussian noise (AWGN) channel. The closed-form derivation of the capacity shows the impact of scenario and transmission parameters on the two coexisting systems and allows to choose the best CR strategy.
