In such a system model, we discuss the unsolved Opportunistic Spectrum Access challenges to be addressed in the consequent chapters. Namely, the inability of current spectrum sensing schemes to accurately assess the spectral opportunities based only on the local interfer

More specifically, we find the values of the probabilities . and . as well as the maximum secondary transmission rates and powers that maximize the average rate of a secondary user whi
