中文摘要：

网络编码协作中继技术能合理分配IMT—Advanced的资源，从而提高系统性能，受到了广大学者的关注。针对基于网络编码的双向多中继协作系统，提出基于混合蛙跳的资源分配方案。以最小化系统传输功率为优化目标，在满足用户QoS下，推导每个节点的最优化功率，建立最优化资源分配模型，利用混合蛙跳算法解决系统资源分配问题。仿真结果表明,在满足单节点QoS下，所提出的基于混合蛙跳的资源分配方案能有效减小系统的总功率，提高系统性能。

英文摘要：

Cooperative relay based on network coding is paid much attention to improve performance due to rational resources allocation in IMT-Advanced system. Resource allocation scheme based on Shuffled Frog-Leaping Algorithm （SFLA） is proposed fnr two-way multi-relay cooperative system with physical network coding. Optimal power to each node is formulated to minimize the transmission power with the individual required QoS and the optimization problem is effectively solved by SFLA. Simulation results demonstrate that the system based on SFLA with the individual required QoS achieves better performance though effectively reduce transmission power.
