The capacity region of a class of broadcast channels with a sequence of less noisy receivers
The capacity region of a broadcast channel consisting of k-receivers that lie in a less noisy sequence is an open problem, when k 3. We prove that superposition coding is indeed ...

The price of certainty: "waterslide curves" and the gap to capacity
The classical problem of reliable point-to-point digital communication is to achieve a low probability of error while keeping the rate high and the total power consumption small. ...
