time delay spread

基本解釋

In the empty rectangular straight tunnel, the influence to the propagation loss and RMS time delay spread of the radio wave is investigated.
由于符號持續(xù)時間的加長，因而它對多徑時延擴展有較強的抵抗力，是對高速數(shù)據(jù)傳輸?shù)囊环N潛在的解決方案。
The wireless propagation environment is described first: analyzing the small-scaled fading, including amplitude fading, multi-path time delay and Doppler spectrum spread.
在本論文中，首先對移動傳播環(huán)境作了描述，特別是對小尺度多徑傳播造成的幅度衰落，多徑時延和多普勒頻移進行了分析；
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計（MLSE）均衡器采用維特比算法（VA），它只能用于具有較小時延擴展的信道。
