Abstract :
An OFDM system optimization for satellite communication in Ka band is estimated in terms of the Shannon theory. The analysis covers a novel closed-form expression for the optimal subcarriers, with respect to the maximization of the achieved spectral efficiency, expressed in terms of the theoretically Shannon channel capacity available to each system´s user.
