为了满足用户的公平性要求,研究了无线非再生中继网络中,基于多用户服务质量(QoS)保证的功率分配策略.首先在总功率受限条件下,提出了最小化最大(min-max)用户中断概率的功率分配方案;然后在中断概率和总功率受限条件下,提出了最大化最小(max-min)用户速率的功率分配方案.上述功率分配问题可转化为几何优化(GP)问题进行求解.仿真结果表明,所提功率分配策略能有效满足用户间的QoS要求. In order to meet the fairness requirement of users, the power allocation strategy based on multi-user quality of service (QoS) guarantee in wireless non-regenerative relay networks is studied.Firstly, under the condition of total power limitation, the min-max ), The power allocation scheme of maximizing the min-max user rate is proposed under the condition of limited interrupting probability and total power. The above power allocation problem can be transformed into the geometric optimization (GP) The simulation results show that the proposed power allocation strategy can effectively meet the QoS requirements among users.
