【Abstract】 Several methods of constructing orthogonal transforms are presented. By means of these methods, new orthogonal transforms having good properties in the spectrum domain can be generated from known orthogonal transforms. The spectra are combinations of window spectra of original orthogonal transforms, wherein the transforms generated by using H product have invariant property of power spectra for cyclic shift. All these methods are new tools for spectrum analysis and digital processing.更多还原
