Multiwavelets have orthogonality, compacted support, and symmetry simultaneously; these properties are very important for signal processing. However, most of multiwavelets require related prefilters. An approach to construction of a symmetry/antisymmetry orthogonal filter is proposed and the corresponding balanced filter is constructed, no any prefilter is necessary. Experimental results show its performance to be superior to DGHM and CL multiwavelets, closer to or higher than Bi9/7.
