A Full Rate Symmetrical Cooperative Relay Approach for Wireless Systems

Cooperative relaying methods have attracted a lot of interest in the past several years. A conventional cooperative relaying scheme has a source, a destination and a single relay. Since it can extend the coverage of wireless systems, this cooperative technique can support one symbol transmission per time slot, called full rate transmission. However, existing full rate cooperative relay approaches are non-symmetrical for different symbols. In this paper, we propose a cooperative relaying scheme that is assisted with dual relays and provides full transmission rate and the same macro-diversity to each symbol.
