伪码调相的硬件设计与实现

The Design and Implementation of Pseudo Random Code Phase Modulation

伪码调相可实现精确定距,有着广泛的应用前景。根据伪码调相的实现机理,重点讨论了相关关键环节的设计与实现,并测试了调制信号频谱图,结果表明所设计的硬件电路能实现具备较高信噪比的伪码调相调制信号。

Pseudo Random Code Phase Modulation can be used in the area of accurate distance control. It has a comprehensive applying expectation. This paper analyses the principle of Pseudo Random code modulation system, illustrates the design and implementation of several key units, and gives the testing spectrum.The results show that the design scheme discussed in this paper can provide the Pseudo Random Pulse Modulation signal with superior signal to noise ratio.
