%X ODWT (Orthogonal Discrete Wavelet Transform) is translation-variant, which will depress the compression efficiency. To avoid the deficiency, by holding all the even and odd indexed subsamples in every scale, a bitree structure is formed here. From any route of the bitree the signal can be reconstructed. According to sonic given criterion, a best transform route can be determined. The simulations show that the compression performance of the best transform route is better than that of the ordinary ODWT.
