摘要 正交多小波可同时具有短支集 ,对称性或反对称性和正交性 ,这是一般的正交单小波所没有的性质。本文详细说明了应用GHM正交多小波对信号进行去噪处理原理 ,并给出实际例子说明该方法的有效性。 Orthogonal multiwavelets can simultaneously have shorter support,symmetry or antisymmetry and orthogonality,while monowavelet function cannot possess such properties.The principle of random noise suppressed by GHM orthogonal multiwavelet is discussed in detail in this paper.The method has been proved to be feasible by a concrete instance.
