摘要 为了提高基于正交频分复用(OFDM)的放大转发模式下双向中继系统总容量,提出了一种低复杂度的基于信道增益排序子载波配对算法(SP-SCC)和一种联合该子载波配对与功率分配的资源优化策略.该策略首先是在等功率的条件下进行SP-SCC方法的子载波配对;然后在系统总功率的限制下,利用对偶分解获得各子载波间的功率分配;最后将各子载波上的功率分配到各节点上,即获得了各节点上最优功率分配.仿真结果表明,所提的资源分配策略可以提高系统总容量. 为了提高基于正交频分复用(OFDM)的放大转发模式下双向中继系统总容量,提出了一种低复杂度的基于信道增益排序子载波配对算法(SP-SCC)和一种联合该子载波配对与功率分配的资源优化策略.该策略首先是在等功率的条件下进行SP-SCC方法的子载波配对;然后在系统总功率的限制下,利用对偶分解获得各子载波间的功率分配;最后将各子载波上的功率分配到各节点上,即获得了各节点上最优功率分配.仿真结果表明,所提的资源分配策略可以提高系统总容量.
