A method for the construction of $p$-adic orthogonal wavelet bases within the framework of the MRA theory is suggested. A realization of this method is illustrated by an example, which gives a new 3-adic wavelet basis. Another realization leads to the $p$-adic Haar bases which were known before.10 pagesGeneral MathematicsMathematical PhysicsPrimary 11S80, 42C40; Secondary 11E95text
