n.副载波(辅助波；用调制其它载波的载波；副载频)
A method and apparatus for subcarrier selection for systems is described. 本发明公开了用于系统的副载波选择的方法和设备。
Moreover, the subcarrier paring strategy can further enhance the system performance. 通过子载波配对方案能进一步增强系统性能。
A small reference packet of the subcarrier sine wave, typically 8 or 9 cycles, which is sent on every line of video. 子载波正弦波的一种小型参考数据包，通常有8或9个周期，在视频中的每一行发送。
Meanwhile, a subcarrier paring strategy for two hops was proposed based on the immunity genetic algorithms (IGA). 仿真结果表明，资源联合优化与传统的平均资源分配相比，显著提高了系统容量。
Based on this,a subcarrier pair selection method is given by applying the Hungarian algorithm. 然后利用匈牙利算法进行中继子载波对选择;
