摘要
Abstract
Power control is critical for cognitive radio a network that allows spectrum sharing among secondary users and primary users. In this paper, an optimal distributed power control strategy was derived aiming at the total capacity maximization of secondary network with interference constraints to primary users.Due to the nonconvexity of system utility, geometric programming was introduced to transform nonconvex optimization problems into convex optimization problems. The auxiliary variables and extra equality constraints were introduced to transfer the coupling in utility to coupling in constraints. The solution of the proposed power control strategy was shown to be globally optimal and led to excellent performance.关键词
