Full-duplex cooperative uplink communication is an effective method to realize the power-efficient long-distance transmission, especially for terminal devices with limited energy. It can obtain diversity gains and improve transmission rate along with low energy cost. In this paper, we introduce a recursive design approach of new non-full-diversity space-time codes for arbitrary number of terminal devices in the full-duplex cooperative communication to suit the actual distributed networks. Then we propose open-loop and close-loop power allocation strategies which allow symbols with different diversity gains to achieve the similar performance, thus enabling optimal system performance. Additionally, subcarrier mapping is employed to make sure fairness of energy consumption between devices. The simulation results show that our proposed system for multiple devices performs better than existed systems for limited number of devices. Also, our proposed optimization method can eliminate the performance differences between symbols and improve the system performance dramatically in terms of bit error rate and transmission distance.
