Abstract :
In this comment, it is shown that the semi-numerical algorithm for computation of the ergodic channel capacity, which has been suggested in the paper cited by the headline above, can be replaced by a closed-form solution - either based on generalized hypergeometric functions or, in a more concise and elegant approach, on Meijer´s G-function.
