frequency selectivity meaning in English
频率选择性
Examples
- Low losses and frequency selectivity at the same time
能，低消耗和同步的频率选择功能。 - Acent frequency selectivity
邻近频率选择性 - Much attention has been paid to it , because the system can achieve better performance than conventional cdma in high data applications and it is potentially robust to channel frequency selectivity
Cdma技术和ofdm技术结合产生了多载波cdma系统，它很好地解决了高速数据业务下传统cdma系统性能下降等一系列问题。 - Finally , this thesis put forward the application of frequency diversity reception to the counteraction against the frequency selectivity decline in the airborne oceanic submarine laser communication system , and whose capability graph is educed through the simulation on the computer
文中提出把频率分集接收技术应用于对潜通信中，以达到抗频率选择性衰落的目的，并通过计算机模拟得出了其性能曲线。 - Stfs is a good coding arithmetic which is simple and easy to realize . moreimportantly stfs has higher diversity order and encoding gain than sts at the samesymbol rate . it can repel channel fading , improve data rate and wireless systemcapacity availability , stand against frequency selectivity fading , eliminate theintersymbol interference
该编码算法不仅在方法和原理上简单,而且易于实现,在相同符号率下比空时扩频具有更大的分集度和更高的编码增益,能有效抵抗信道衰落、提高数据速率、提高无线系统容量、很好的对抗频率选择性衰落和消除符间干扰。
