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.
由於符號(hào)持續(xù)時(shí)間的加長，因而它對(duì)多逕時(shí)延擴(kuò)展有較強(qiáng)的觝抗力，是對(duì)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(duì)移動(dòng)傳播環(huán)境作了描述，特別是對(duì)小尺度多逕傳播造成的幅度衰落，多逕時(shí)延和多普勒頻移進(jìn)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(jì)（MLSE）均衡器採用維特比算法（VA），它衹能用於具有較小時(shí)延擴(kuò)展的信道。
