采用广义平稳非相关散射(WSSUS)信道可以较容易地描述随机时变线性信道的性质。它的特性可用散射函数来表示。本文给出了一些测量到的散射函数。给出的散射函数只包括了海况的影响,但观察到的变化经常是由声速跃变层或海平面的变化引起的。在海况局部平稳的时间间隔中这些慢起伏引起不平稳。
The properties of a stochastic time-varying linear channel can be described more easily by using a generalized stationary non-correlated scattering (WSSUS) channel. Its characteristics can be expressed using the scattering function. This article gives some measured scattering functions. The scattering function given only includes the effects of sea conditions, but the observed changes are often caused by changes in the sonic velocity or sea level. These slow fluctuations cause instability in locally stable time intervals at sea conditions.
