Power allocation is a promising approach for optimizing the performance of mobile radio systems in interference channels. In the present paper, the non-convex objective function of the power allocation problem aiming at maximizing the sum rate with a total power constraint is reformulated as a difference of two concave functions. A global optimum power allocation is found by applying a branch and bound based algorithm to the new formulation. The algorithm basically splits the feasible region… CONTINUE READING
