Outage Analysis for Decode-and-Forward Multirelay Systems Allowing Intra-Link Errors

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.
