The increasing demand of wireless data makes the electromagnetic spectrum a scarce and valuable resource. Wireless networks should exploit its available spectrum in the most efficient way to maximize the amount of data they can support. Alternatives to increase the spectral efficiency of wireless networks include the design of new spectrum access paradigms and the operation of existing wireless links in the most efficient way. In this thesis we present two different approaches for increasing the spectral efficiency of wireless networks. The first approach is based on a cognitive-inspired spectrum access paradigm in which a secondary user is allowed to access the frequency bands owned by a primary user. This cognitive access has to be pr...
