Uplink throughput of multi-cell processing with HDAF cooperation between mobiles

Joint decoding at base stations combined with cooperative transmission is investigated to improve the uplink throughput of current cellular systems over fading channels. In this paper, we consider amplify-and-forward (AF), decode-and-forward (DF) and hybrid decode-amplify-forward (HDAF) cooperation schemes between relay stations. We analyze the throughput of direct transmission (DT), AF, DF, and HDAF both in single-cell and multi-cell respectively. A linear mesh network is considered where a single mobile terminal for each cell communicates with a local base station via a dedicated relay, which can be AF, DF, or HDAF. All of the base stations in the mesh network decode the received signals cooperatively.
