On Broadcast Channels With Binary Inputs and Symmetric Outputs

We establish capacity regions for some classes of broadcast channels with binary inputs and symmetric outputs. We investigate the more capable partial order and establish that the binary erasure channel and the binary symmetric channel form the two extremes for channels having the same capacity. Fur...

Zusammenfassung:	We establish capacity regions for some classes of broadcast channels with binary inputs and symmetric outputs. We investigate the more capable partial order and establish that the binary erasure channel and the binary symmetric channel form the two extremes for channels having the same capacity. Further, we apply the results to identify a class of broadcast channels for which the best-known inner and outer bounds on the capacity region differ.
