Abstract EN
Motivated by recent interest in dynamic spectrum sharing between primary and secondary spectrum users, we investigate slow adaptive quadrature amplitude modulation (QAM) under third-party received power constraints.
The optimal rate and power adaptation schemes are derived to maximize the average spectral efficiency (SE) for the secondary users.
Additionally, closed-form expressions of the achievable SE are presented for correlated lognormal shadow fading environments.
Our analytical and numerical results underscore the importance of exploiting shadowing correlation in the proposed adaptive schemes.
