Abstract:
Abstract—A network with two sources, one relay, and one
destination is considered. Under the assumption of noisy sourcerelay
links causing the relay to be unable to decode without error,
we propose a quantizer design framework where the quantizer
jointly compresses the soft information available for both sources
at the relay. The quantizer design is based on the information
bottleneck method using the notion of relevant information as
an optimization criterion.
