In order to reduce the computational complexity, the original optimization problem is decomposed into two steps. In the first step, the subcarrier assignment and relay selection scheme are determined based on equal power allocation.
为降低求解的复杂度,将优化问题分为两个步骤,首先在等功率分配的情况下求出最优的子载波分配以及中继节点选择的方案,然后再根据注水定理进行功率分配。
