time delay spread

常见例句

In the empty rectangular straight tunnel, the influence to the propagation loss and RMS time delay spread of the radio wave is investigated.
由于符号持续时间的加长，因而它对多径时延扩展有较强的抵抗力，是对高速数据传输的一种潜在的解决方案。
The wireless propagation environment is described first: analyzing the small-scaled fading, including amplitude fading, multi-path time delay and Doppler spectrum spread.
在本论文中，首先对移动传播环境作了描述，特别是对小尺度多径传播造成的幅度衰落，多径时延和多普勒频移进行了分析；
The Maximum Likelihood Sequence Estimation (MLSE) using the Viterbi Algorithm (VA) is commonly recommended for the equalization, which can only accommodate the channels with limited time delay spread.
常用的最大似然序列估计（MLSE）均衡器采用维特比算法（VA），它只能用于具有较小时延扩展的信道。
