A method for detecting and estimating the parameters of chirp spread spectrum signals based on Radon-Wigner transform is proposed.
提出了基于Radon-Wigner变换的线性调频扩谱信号的检测方法。
A new definition of linear spectrum of multi-valued logical functions over finite field was proposed.
给出了新的一般有限域上多值逻辑函数的线性谱定义,并对两类谱的转换公式做了进一步简化。
We firstly redefine the Chrestenson linear spectrum of logical functions over Finite Fields, which was ever offered in [1].
本文首先给出了有限域上逻辑函数的Chrestenson线性谱的新定义(不同于文献[1]所给出的),如同Chrestenson循环谱一样,重新定义的Chrestenson线性谱也是有限域Fq到复数域的映射,且证明了它们之间在实质意义下可以相互线性表出;最后我们还用重新定义的Chrestenson线性谱给出了有限域上逻辑函数的反演公式。
