Abstract :
We consider the problem of cooperative precoder selection for interference management in a broadband cellular wireless system. The problem is posed as a sum-rate maximization problem and a solution employing distributed scheduling and precoder selection is proposed. The solution is then shown to be optimal under certain asymptotic conditions. This is also verified using system simulations.
