Compared with the point-by-point scanning method and algorithm of area filling, this new algorithm has no necessity not only in point-by-point calculation...
Convolutive Blind Source Separation based on Wavelet De-noising
Hongbin Zhang, Pengfei Xu
The paper discusses the time-domain blind seperation applied to communication signals, using an ICA algorithm EFICA together with a wavelet de-noising processing method. In the Blind source separation system, regardless of the mixed signals and separated signals, noise pollution occurs frequently, it...

Gear fault diagnosis method of intelligence based on genetic algorithm to optimize the BP neural network
The work of the gear transmission is very complex, and its failure in the form and features tend to show non-linear mapping. Fault signal is often submerged in conventional vibration signal and noise, it is not easy using traditional signal processing methods to extract fault features which in a difficult...
A Study on Grey Correlation Degree Model of Venture Capital Intrinsic Value
In view of the disfigurement that the former research mostly focus on the evaluation of the investment value before investment, not only this paper uses for reference to the former evaluation system, but also successfully integrates it into a unity that the evaluation before investment and after investment....
