An Improved Transmission Rate Achievement in Cooperative Communication System Based on OFDM
نویسندگان
چکیده
Recently, cooperative system is an interesting issue in communication systems. Single mobile antenna can have transmission diversity gain by the cooperative system as multiple input multiple output (MIMO) system. However, the most of the cooperative systems have a problem about the transmission rate loss. In this paper, hierarchical modulation is proposed in order to solve the transmission rate-loss in the cooperative system.
