共轭对称和共轭反对称新序列的构造与应用

Configuration and Application of New Conjugate Symmetric &.Conjugate Antisymmetric Sequence

本文通过对共轭对称序列和共轭反对称序列的分析,指出了一种构造新序列的方法,新序列保持了原序列的性质,用途却比原序列要广。文章着重讨论了新序列在DFT(Discrete Fourier Transform)方面的应用,通过计算一个复序列的N点DFT,便可获得四个实序列的N点DFT。

In this paper, the author points out the method of configuring a new sequence by analysing the conjugate symmetric sequence and the conjugate antisymmetric sequence. The new sequence maintains the properties of the original sequence and has wider uses than the original one. The author introduces the application of the new sequancc in the Discrete Fourier Transform (DFT). We can get the N-point DFTs of the four real se-quences by computing the N-point DFT of the complex sequence.
