Abstract :
This paper first identifies a flaw in the proof of the convergence theorem of Algorithm 2 of the paper by Jindal [“Sum power iterative water-filling for multi-antenna Gaussian broadcast channels,” IEEE Trans. Inf. Theory, vol. 54, no. 4, pp. 1570-1580, Apr. 2005] and then presents a corrected convergence proof for that algorithm.
