Abstract
To study the fairness-optimization problem with different user-rate in non-regenerative relay network,a power allocation algorithm based on user-required rate proportional fairness was proposed.Because the source could not receive the messages of the user's hope rate,a pre-average allocation fairness algorithm was proposed to overcome the disadvantage of the prior algorithm.The simulation results show that the two algorithms realize goal of minimizing the difference between user-rate and required rate and save the resource in network with assuring the users' requirement of Quality of Service(QoS).
