Comments on 'Dual methods for nonconvex spectrum optimization of multicarrier systems'

摘要

Yu and Liu's strong duality theorem under the time-sharing property requires additionally the Slater regularity condition to hold for the considered general nonconvex problem, which is naturally satisfied for the specific application. We further extend the scope of the theorem under Ky Fan convexity, which is slightly weaker than Yu and Lui's time-sharing property.
