We derive the expressions of the outage probability for a wireless network that integrates hybrid automatic repeat request (HARQ) and coded cooperation among nodes. The medium access control (MAC) provides a HARQ protocol where the source node, upon a decoding failure at the destination node, transmits additional coded bits for the same data packet. If a neighbor node is able to decode the first transmission, it cooperates with the source by sending additional coded bits. In order to keep nodes simple, we assume half-duplex, single band asynchronous transmissions, and receivers with single user detection techniques. Various configurations of cooperation are considered and the analysis includes key characteristics of wireless communications and interference.

Abstract
We derive the expressions of the outage probability for a wireless network that integrates hybrid automatic repeat request (HARQ) and coded cooperation among nodes. The medium access control (MAC) provides a HARQ protocol where the source node, upon a decoding failure at the destination node, transmits additional coded bits for the same data packet. If a neighbor node is able to decode the first transmission, it cooperates with the source by sending additional coded bits. In order to keep nodes simple, we assume half-duplex, single band asynchronous transmissions, and receivers with single user detection techniques. Various configurations of cooperation are considered and the analysis includes key characteristics of wireless communications and interference.Pubblicazioni consigliate
