Abstract

Bounds on the cardinalities of auxiliary random variables needed to compute the Cover-van der Meulen region R are obtained for the situation when no common message is sent and the broadcast channel input is binary. These Thes bounds are obtained via a new representation theory for auxiliary random variables. An extension of this result to the ternary input Blackwell channel is outlined. By actually computing a certain rate region for some examples, it is demonstrated that the general Cover-van der Meulen region R may be enlarged to a new achievable region. This enlargement is accomplished by making R internally consistent, as the true capacity region must be. Our results display complex interactions between common and separate information in broadcast problems.
