On the sufficiency of power control for a class of channels with feedback
International Symposium onInformation Theory, 2004. ISIT 2004 …, 2004•ieeexplore.ieee.org
This paper shows that, for a particular class of channels that we believe applies to many
physical problems of interest, the utility of feedback, insofar as channel capacity is
concerned, is simply for allowing the transmitter to perform power control. This class of
channels, which assumes noiseless feedback but allows for the feedback to be of arbitrary
rate, includes channels that model slow, flat fading channels with variable input power. Thus
our result gives some guidance on the design of effective transmission schemes for slow, flat …
