Cooperative Transmission Scheme with Two Relay Stations and Phase Feedback Channels


In this paper, we propose a new transmission scheme with two relay stations and phase feedback channels between the relays and the destination node. The preprocessor use in the relay stations is managed to achieve a full diversity order and also an array gain at the destination node. A phase feedback investigation for the proposed scheme is presented assuming quasi-static flat Rayleigh fading channels. An analysis of the relay spatial allocation design is also performed.
