【Abstract】 In this paper,we give the sub-quadrature mirror filter(sub-QMF) condition about the multiwavelet frame,and propose the complete method that constructs corresponding high-pass filters based on design of lowpass filters using unitary matrix extension.And aiming at the multiple description coding,we design two-length parametric multiwavelet frames with asymmetrical folds.更多还原
