Abstract: Wavelet is introduced to the estimation of the Long Memory Stochastic Volatility(LMSV)model,and the wavelet transformation based estimation method of parameters and volatility process is proposed on the bases of the wavelet analysis results of ARFIMA process.The method suggested is proved to be effective and feasible by the simulation experiments with different parameters value and different series length as well as the estimation of LMSV model of the return series of aggregate index of Shanghai and Shenzhen stock markets.

Key words: wavelet transformation, LMSV model, ARFIMA process, estimation
