Uplink Throughput of Multi-cell Processing with HDAF Cooperation Between Mobiles

Abstract—Joint decoding at base stations combined with co-operative 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. Keywords—Cooperation, amplify-and-forward (AF), decode-and-forward (DF), hybrid decode-amplify-forward (HDAF). I
