Abstract
In this paper we derive a sufficient condition under which the iterative water-filling (IWF) algorithm with quantized noise-plus-interference levels is guaranteed to converge and has a unique Nash equilibrium. This condition is shown to approach the corresponding condition for standard IWF when the quantization resolution or the transmission powers are sufficiently high.
