衰落效应 meaning in Chinese
fading effect
Examples
- Contributions in this paper mainly sh ow four points : 1 the structure characteristic of the received ds - cdma signal is analyzed in the presence of multi - path slow fading effect case for wireless mobile communication . according to this characteristic , four data - selected schemes based on chip - matched filter are presented from the perspective of energy and structure of signal . and the impact of these schemes on multiple - access interference ( mai ) and inter - symbol interference ( isi ) is analyzed
本文的主要贡献在于四个方面： 1 、针对无线移动通信系统中广泛存在多径慢衰落效应的情况，分析了ds - cdma系统中接收信号本身的结构特征，根据这个特征，在匹配滤波的基础上，从能量与信号结构的角度提出了四种不同的数据采用方案，并分析了不同数据方案对多址干扰与码间干扰的影响。 - This paper proposes a multiple description mesh - based motion coding method , which generates two descriptionsfor mesh - based motion by subsampling the nodes of a right - angledtriangular mesh and dividing them into two groups . motion vectorsassociated with the mesh nodes in each group are transmitted overdistinct channels
丢包由于网络阻塞路由延迟以及从高容量网络向低容量网络交换等和信道失效由于衰落效应和突发错误等使得在internet和无线信道上压缩视频数据的可靠传输成为新的研究课题。 - Underwater acoustic communications ( uwa ) are made difficult by the combined effect of multipath propagation and high temporal and spatial variability of the channel conditions . the fading which was caused by multipath propagation was one of the main factors influencing the performance of underwater acoustic communication systems
水声信道中广泛存在的多径传播效应是水声通信所面临的主要障碍之一，由多径所产生的信号衰落效应是影响水声通信系统性能的主要因素之一。
