Résumé:
In this paper, we study the problem of resource
allocation for an opportunistic spectrum-sharing channel under
the assumption of statistical channel state information (CSI).
More specifically, we assume that statistical CSI of the channels
between both primary and secondary transmitters and the
primary receiver is available at the secondary transmitter. We
investigate the achievable rate maximization of both primary and
secondary systems with successive interference cancellation (SIC)
under outage, interference limit, and total power constraints.
We deal with the secondary non-convex optimization problem
by using the first order Taylor approximation. We propose a
sequential convex approximation algorithm to solve the power
allocation problem. Simulation results establish the efficiency of
our proposed algorithm.
