The capacity of a Gaussian channel with feedback can at most double, as shown by Professor Thomas Cover and his students at Stanford University. But the fact that feedback does not improve the capacity much remains to be shown matematically. You may write to Prof. Cover to find out the status of this research problem. His address is Prof. Thomas M. Cover Durand Bldg., Rm. 121 Department of Electrical Engineering Stanford University Stanford, CA 94305 By the way, this is an excellent question. It is not covered by almost all communications or coding theory books, which only discuss technical methods of using feedback. So it is worthless to look into the books for the answer. This is a question whose answer is a good research problem, for a Ph.D. dissertation for instance.
