Summary:A special case of the general discrete memoryless relay channel is
studied. This channel consists of an input x, a relay output
z, a channel output y, and a noiseless channel of
capacity Cr allowing the relay sender to send
additional information to the decoder. The channel is described by a
collection of distributions {p(y,
z|x)}. The decoder uses the channel output y
and a function f(z) of the relay output at a rate no
greater than Cr to recover the message. Some results
on the capacity of the channel are obtained
