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Qo S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Qo S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。
Network coding cooperative relay technology can reasonably allocate resources of IMT-Advanced to improve system performance, and has attracted the attention of the majority of scholars. Aiming at the bidirectional multi-relay cooperative system based on network coding, a resource allocation scheme based on hybrid frog leaping is proposed. In order to minimize the transmission power of the system as the optimization objective, the optimal power of each node is derived under the user Qo S, and the optimal resource allocation model is established. The mixed frog leap algorithm is used to solve the system resource allocation problem. The simulation results show that the proposed resource allocation scheme based on hybrid frog leaping can effectively reduce the total power of the system and improve the system performance under a single node Qo S.
