摘要
为提供中继蜂窝网络相关技术的验证平台,通过将中继场景加入传统LTE-Advanced网络中,利用模块化的仿真方法,设计实现LTE-Advanced中继系统级仿真平台。针对传统服务节点选择算法的不足,提出一种基于联合优选的服务节点选择算法;利用该平台将3种传统服务节点选择算法与联合优选服务节点选择算法进行仿真比较。仿真结果表明,与3种传统算法相比,联合优选算法提升了用户信干噪比,降低了算法复杂度,验证了该系统级仿真平台的有效性。
To provide the relay cellular network technology verification platform, by adding the relay scene to the traditional LTE-Advanced network and using the modular simulation method, the LTE-Advanced relay system level simulation platform was designed and implemented. To overcome shortcomings of the traditional service node selection algorithm, the joint optimal service node selection algorithm was proposed. Then this platform was used to compare the three kinds of traditional service node selection algorithms and the joint optimal service node selection algorithm. Results of the simulation indicate the proposed joint optimal algorithm has higher SINR and lower complexity than the three kinds of traditional algorithms, at the same time the effectiveness of the system level simulation platform is verified.
