延迟扩展 meaning in English
delay spread
Examples
- For this method , it provides an improved performance in the channel environment with a large delay spread , and hence can be utilized in the ofdm systems especially for the broadcasting systems
在延迟扩展很大的通道环境中，使用此估计非码际干扰区间的方法，在性能上有较为显著的提升，适合应用在广播系统这一类的正交分频多工系统中。 - However , to achieve this objective , various technical challenges must be overcome . for example , the deployment of broad - band wireless access systems would require a transmission technique which can mitigate the detrimental effects of frequency selective fading
为达到这一目的，有一些技术问题必须得到良好的解决，比方说在宽带通信模式下由于延迟扩展造成的频率选择性扩展和由多普勒效应产生的信道时域衰落。
