本文提出了构造正交变换的几种方法。应用这些方法
可以由已知的正交变换生成新的正交变换。新的正交变换具有良好的谱域特性
它们的谱是原正交变换的窗谱组合
其中由H积生成的正交变换还具有对于循环移位的功率谱点不变性。
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.
