1, with frequency interference



Those who have other wireless signal source to send out the useful signal and the frequency of the same, and in the same way into the receiver intermediate frequency passband wireless interference are called with frequency interference. When interference signals and useful signals into the receiver also be amplified, detection, when two signal carrier frequency difference will appear to beat interference; When two signal modulation is not big, will cause distortion interference; When two signal will cause distortion interference existing phase difference. The interference signal, the noise of the receiving the strong, until not able to answer. This kind of phenomenon is mainly due to the same frequency wireless communication equipment around using the distance is too close interaction effect results, may be illegal radio, it is also possible that WuWei assigned frequency legal radio stations frequency reuse, but is caused by the close. It should be said that this kind of interference is more likely to find the source of the disturbance to solve.
