INEXACT PROJECTION METHOD FOR THE VARIATIONAL INEQUALITIES OVER THE FIXED POINT SET AND ITS APPLICATION TO CDMA DATA NETWORKS

Abstract

We propose a new iteration method for solving variational inequalities over the fixed point set of a firmly nonexpansive mapping, where the cost functions are continuous and not necessarily monone, which is called the inexact subgradient method. One application of the problem is a power control for a direct-sequence code-division multiple-access data network. Finally, we present some numerical experiments to illustrate the behavior of the proposed algorithms.
