摘要：

To minimize the total transmit power of two-way opportunistic relay systems, the joint relay selection and power allocation problem are investigated subjecting to two constraints on the transceivers' received signal-to-noise-ratios(SNRs). The outage probability is analyzed when the proposed power allocation is adopted. Simulation results show that: the total transmission power is substantially decreased by the proposed power allocation scheme when two transceivers have different quality of service(QoS) requirement; the outage probability matches the theoretical analysis perfectly.
