1) signals aliasing
信号混叠
1.
In accordance with the method of FFT frequency analysis,the phenomenon of signals aliasing and leakiness at the turbine pressure fluctuation test is introduced.
通过对大量试验资料的分析 ,针对目前广泛使用的FFT分析法 ,介绍了在水轮机压力脉动试验过程中可能产生的信号混叠和信号频率泄漏现象 ,提出了在采用FFT分析时较为合理的信号采集方法。
2) aliasing signal
混叠信号
1.
The seismic observation signal is equivalent to the linear aliasing signal taking above four elementary structure factors as signal source.
地震观测信号可等效地看成是地下地质体4个"基本结构因子"信号源的线性混叠信号,利用独立分量分析技术(ICA)可从混叠信号中提取出这些相互独立的信号源,从而可提取出隐含在地震观测信号中的含油气性(流体属性)和沉积相(骨架属性)等有用的信息。
3) Overlapped communication signals
混叠通信信号
4) overlapped frequency-hopping communication signals
混叠跳频信号
1.
For the separation of overlapped frequency-hopping communication signals,a method is expounded to adopt the FastICA(Independent Component Analysis) algorithm to separate overlapped frequency-hopping communication signals,based on researching independent component analysis theory deeply,and aiming to the characteristic of frequency-hopping Communication.
为解决混叠跳频信号的分离问题,在深入研究独立分量分析(ICA:Independent ComponentAnalysis)理论基础上,结合跳频通信的特点,提出了基于独立分量分析的混叠跳频信号分离算法,实现了对混叠跳频信号的盲分离。
6) aliasing noise
混叠噪声;假信号噪声
