Power control for non-Gaussian interference

This paper investigates the power control problem involving a small number of active users whereby the standard Gaussian interference noise assumption does not hold. The model also allows for different user transmission rates. We analyze the situation under which the system can be asymptotically error-free. Subsequently, we formulate a power control optimization problem and propose an iterative descent algorithm for solution. We prove that under suitable conditions, the power control optimization problem has a unique solution which is achieved by the proposed algorithm. Simulations are carried out and compared with the power control results under the classical Gaussian assumption.
