Some Properties of a Class of Wiener Dierence Processes and Wavelet Express
Xuewen Xia · 2013
Recently, some researchers have studied wavelet problems of stochastic processes or stochastic system by using wavelet. In this paper, we take wavelet and use it in a series expansion of signals or functions. Wavelet has its energy concentration in time to give a tool for the analysis of transient and nonstationary and time-varying phenomena. Wavelets have contributed to this already intensely developed and rapidly advancing eld. The study of Wiener dierence processes stochastic system is very important in theory and application. In this paper, Wiener dierence processes are studied by using wavelet analysis, and some properties and wavelet express are obtained.
