Description: In this paper, we focus on the general relay channel.
We investigate the application of the estimate-and-forward (EAF)
relaying scheme to different scenarios. Specifically, we study
assignments of the auxiliary random variable that always satisfy
the feasibility constraints. We then consider the Gaussian relay
channel with coded modulation, where we show that a three-level
quantization outperforms the Gaussian quantization commonly
used to evaluate the achievable EAF rates in this scenario. Last,
we consider the cooperative general broadcast scenario with
a multistep conference between the receivers. We first apply
EAF to obtain a general achievable rate region with a multistep
conference. We then use an explicit assignment for the auxiliary
random variables to obtain an explicit rate expression for the
single common message case with a two-step conference.
