## Abstract

In the Gaussian listening-helper source-coding
problem Encoder 1 and Decoder 1 observe respectively a pair of
i.i.d. correlated Gaussian sources and both wish to communicate
the first source to Decoder 2 subject to a distortion constraint.
Encoder 1 sends a message to both decoders and then Decoder 1
– the listening-helper – sends a message just to Decoder 2.
We derive an inner bound on the rate region of this problem
by proposing a Gaussian achievable scheme. This inner bound
coincides with the solution to the Gaussian optimization problem
associated with a single-letter outer bound corresponding to this
problem.
