摘要

The main purpose of this paper is to investigate the wavelet moving average sequences which are based on the orthonormal wavelet basis. It may be shown that the WMA sequence also possesses the truncated property as that of the traditional MA series. Under some mild mathematical conditions, it has been proved by the author that the projection of a stationary series from the space to subspaces may form a non-stationary WMA sequence.
