Abstract

In the context of distributed source coding, the so-called many-help-one problem comprises a set of auxiliary sources aimed at helping the decoder retrieve a primary source. In this letter, we build on the newly derived admissible rate region of a certain binary many-help-one problem to obtain the outage probability (OP) of a decode-and-forward (DF) multirelay system that allows intra-link errors (IE) to be forwarded to the destination. In addition, for comparison, we obtain the OP of a conventional DF multirelay system, which discards any IEs. We show that, the more relays are employed, the more advantageous it is to forward the IEs, as opposed to discarding them. (AU)
