摘要
本文介绍利用希尔伯特变换原理设计信号解调软件.分析比较了实现离散希尔伯特变换的方法,提出了相位解调运算中相位补偿方法。该软件以各种计算机模拟调制信号为例进行分析,取得满意效果。
In this paper,the design of demodulation software using Hilbert Tras- form Principle is introduced.And the methods realizing Discrete Hilbert Transform are discussed.Also,the way of phase compensation in phase de- modulation is proposed.In addition,this software has been used to analyze various computer simulated modulated signals and satisfactory results were obtained.
