... capacity of the latter class of channels as well. This result was originally obtained in [8]. This is stated in the following corollary. Since the proof of this corollary is similar to the proof of ... reminiscent of the result in [25, 26] about the optimality of the use of independent inputs in each subchannel for the product of two degraded broadcast channels. As mentioned...
