To improve the robustness and the coverage, new words are initially annotated with the dependency relation of the highest frequency corresponding to its partofspeech.
在测试时，对新词标注以该词词性所对应的最高频的依存关系作为初始标注以提高鲁棒性。
The capacity, network organizing, coverage, link budget and frequency planning are discussed.
探讨了系统容量、组网、覆盖范围、链路预测和频率规划等内容。
Repeaters have to be employed in metros to meet the coverage requirements because leakage cables and free Spaces are much more spoiled due to high frequency of 3g signal.
由于3g信号频率高，在地铁中的泄漏电缆损耗和空间损耗将大大增加，为了达到覆盖要求，必然要引入中继放大。
High frequency skywave over-the-horizon radar can provide a wide coverage beyond the horizon by means of refraction within the ionosphere.
