Cooperative hybrid ARQ networks

In this work, the performance contribution of a relay node which cooperates to a source node during the transmission of data packets from source node to destination node is investigated. The effect of diversity gain to the performance of a network consists of correlated flat-faded Rayleigh channels. In this work, the re-transmissions of an individual packet are combined at destination node by employing maximal-ratio combining (MRC) method. To model the packet errors for convolutionally coded packets, an approach to ease the analytic investigation is followed.
