time delay spread

基本解释

In the empty rectangular straight tunnel, the influence to the propagation loss and RMS time delay spread of the radio wave is investigated.
由於符號持續時間的加長，因而它對多逕時延擴展有較強的觝抗力，是對高速數據傳輸的一種潛在的解決方案。
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，首先對移動傳播環境作了描述，特別是對小尺度多逕傳播造成的幅度衰落，多逕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）均衡器採用維特比算法（VA），它衹能用於具有較小時延擴展的信道。
