| Abstract | In cooperative transmission users are allowed to share antennas to transmit their messages to a common destination. Users employ either amplify-and-forward or deco deand-forward strategies to forward each others’ messages. In network-coding-based cooperative transmission scheme s, users are allowed to combine their own and their partner’s message by a network-coding operation. This work analysis the outage probability of a network-coding-based decodeand-forward cooperative transmission scheme, when non-id eal inter-user channels exist. A modulo-2 summation is used to implement the network coding, and transmissions are done us ing time division duplex channels. At the destination, iden tical messages are combined using either Selection combining or Maximum-Ratio combining. The numerical results show that a diversity order in the range of two can be obtained using this scheme, taking point-to-point transmission as a basel ine. The work is extended to goodput analysis, based on feedback from the destination. |
