guard intervals meaning in Chinese
保护间隙
Examples
- The effects , caused by rms delay spread estimation , on choosing the right guard interval length is also discussed . simulation results are given as well
分析了rms时延扩展估计误差对于保护间隔长度选定的影响，并给出仿真结果。 - Later , simulates the ofdm system by matlab software , researchs the effect about ofdm system by mapping , guard interval , sub - carrier and channel
然后通过matlab软件对ofdm系统进行了仿真分析，研究了调制映射，保护间隔，子载波和信道对ofdm系统的影响，并得出了一些结论。 - The advantages and drawbacks of the traditional ofdm systems are fully analyzed . hoping to overcome the drawbacks , the aofdm system is designed . the concept of variable guard interval is introduced into aofdm system for the first time
分析了传统的ofdm所存在的优缺点，在此基础上提出了aofdm系统，并首次将可变保护间隔的概念引入aofdm系统。 - Based on the cyclic prefix property of the guard intervals , it provides estimates for sampling positions of isi - free region by combining the techniques of delay conjugate multiplication , phase difference , symbol - by - symbol average , and edge detection
以护卫区间循环前置的特性为基础，结合延迟共轭相乘、相位差分、符元对符元之区段式平均以及边界侦测等技术来估计非码际干扰区间的位置。 - To increase the spectrum efficiency of the ofdm system , a novel aofdm ( adaptive ofdm ) system , which can change its modulation type and length of guard interval according to the estimated channel information , is designed
为了提高ofdm的频谱效率，我们设计了一个能根据信道特征动态改变其调制方式以及保护间隔的自适应ofdm ( aofdm ， adaptiveorthogonalfrequencydivisionmultiplexing )系统。
