英文摘要：

Power optimization scheme for multi-relay cooperative communication system under the constraint of total power is considered.Quantum genetic algorithm is applied in power allocation to maximize system capacity,thereby,power allocation scheme based on quantum genetic algorithm is proposed,and the effect of the system bit error rate with power allocation scheme is dicussed.Compared with equal power allocation（EPA） and power allocation scheme based on genetic algorithm,simulation and numerical results demonstrate that the system based on quantum genetic algorithm achieves better performance with low bit error rate.
