衰减信号 meaning in Chinese

fading signal

In this paper , we analyzed the theory of several linear methods for the pole extraction , such as prony method , kt method and matrix pencil method . then , numerous results based on scattering responses synthesized from weighted sums of two exponentially damped sinusoids are provided to compare theirs performance
本文主要分析了几种极点求解线性算法? ? prony法、 kt法、矩阵束法的基本原理,并比较了这几种算法对于只含两个指数衰减信号模型参数估计的仿真结果。
