... Processing convergence analysis of IWFA in more realistic channel set- tings and for arbitrary number of users. Our approach is based on a key new result that establishes a simple reformu- lation of the noncooperative ... (LCP) of the “copositive-plus” type [7]. Based on this equivalent LCP reformulation, we establish the lin- ear convergence of IWFA for arbitrary symmetric inte...
