Principle of radio interference
The radio interference signal mainly enters the electromagnetic energy of the channel or system of the receiving device through direct coupling or indirect coupling. It can affect the reception of the received signal required for radio communication, resulting in performance degradation, quality deterioration, information error or loss, and even resistance. Broken communication. Therefore, it is generally said that a useless radio signal causes a deterioration or damage to the quality of reception of a useful radio signal, which is called radio interference.
