WebFeb 14, 2024 · 2.3. Gini index-based periodicity measure. For periodic impulses, x (t), focus is set on its second-order cyclo-stationary indicator related to the period of repetitive impulses.Therefore, the SE, E (t), is used to extract the periodic modulation of signal x (t).Moreover, the unbiased autocorrelation of E (t) is calculated to reduce the noise and … WebMar 10, 2024 · In the example shown in Figure 2, stationary noise with an arbitrary PSD is modulated by a periodic signal. This is representative of both ways in which cyclostationary noise is generated (modulated noise sources and modul ated signal paths). It is also representa-tive of how noise is modulated in many types of circuits. In a mixer, the noise ... fobus mag pouch https://eurekaferramenta.com

WebCyclostationarity properties of modulated signals can be suitably exploited in the analysis and design of communications systems since the signals involved are typically almost cyclostationary (ACS). Most techniques are based on the signal selectivity property of cyclostationarity-based detection and estimation algorithms (Section 9.2 ). WebDec 31, 2010 · Traditionally, this analysis is performed by the use of signal processing methods, which assume statistically stationary signal features. The paper proposes an alternative framework for analyzing bearing vibration signals, based on cyclostationary analysis.

WebJul 22, 2024 · Cyclo-non-stationary (CNS) signals are firstly proposed to describe vibration signals recorded under strong varying regimes. These signals, though being resampled in the angular domain, present strong long-term statistical change in their structure that prevents them to be cyclostationary. WebThe fault feature of wind turbine bearing is usually very weak in the early injury stage, in order to accurately identify the defect location, an original approach based on optimized cyclostationary blind deconvolution (OCYCBD) and singular value decomposition denoising (SVDD) is put forward to extract and enhance the fault feature effectively.
