关于能量算子解调方法的研究

Study on a New Demodulation Approach——Energy Operator

能量算子（ＥＯ）解调法是近年来在国外受到重视的一种新的解调方法，本文在介绍其原理的基础上，把这种新的解调方法与作为标准解调法的Ｈｉｌｂｅｒｔ变换法进行了比较。比较了它们的运算速度和解调精度。结果表明，能量算子解调法在运算速度和解调精度方面具有明显优势。

In recent years, more attention overseas is paid to energy operator, a new demodulation approach. On the basis of introducing the principle of the demodulation approach, this paper makes a comparison between the approach and the standard demodulation method based on Hilbert transform. The computing duration and the demodulation accuracy are compared. The result shows that energy operator demodulation approach has obvious advantages in the two aspects over the Hilbert transform demodulation method. It is believed that the energy operator approach plays an important role in signal demodulation.
