Abstract
In this paper, we consider a CR system that uses the LTE-Advanced (LTE-A) standard at the physical layer, and present an algorithm for shaping the spectrum of the corresponding OFDM signal that enables secondary access to the frequency spectrum in dynamic scenarios. The proposed algorithm is based on OFDM precoder adaptation and is illustrated with numerical results obtained from simulations.
