Abstract

This invention discloses a signal phase tracking network used to track the signal phase of multi reference sources, comprising: the original vibration source providing original vibration signal to track the reference source signal; the clock driver driving original vibration source to output multi signals to track multi corresponding reference source signals; the multi phase adjusting circuits each connect to the signal output end of clock driver, the above phase adjusting circuits are used to track one route reference source signal due to one route signal outputted by original vibration source and adjust the signal phase of origin vibration source in this route according to the result of tracking and checking. The invention provides multi original source signal by the clock driver, so it can track multi reference source signal, because it only uses one original vibration source, so the reliability is improved relatively.

Description

technical field [0001] The present invention relates to signal tracking technology, more specifically to a signal phase tracking network. Background technique [0002] Usually, the signal transmitted in communication has two attributes of frequency and phase. The processing based on the change of signal frequency and phase is the basis of modern communication. As one of them, signal tracking technology is also constantly developing. Signal tracking technology refers to tracking and detecting signal changes (including frequency changes or phase changes, etc.) to achieve the purpose of further controlling signal transmission. It has an important position in communication and is widely used in various industries, especially involving In the communication industry, such as aerospace communication, satellite communication and mobile communication, signal tracking and detection are all essential parts. There are many existing signal tracking technologies, but the basic principles...
