Jamming signal can be defined as a signal that affects communication. When an interfering signal enters the receiver, it will affect the normal decision process. According to its formation mechanism, it can be divided into two types: one is additive interference and the other is multiplicative interference.

Additive interference can be regarded as a noise-like source, including noise from other similar systems, within the system, or nonlinearly generated by components (intermodulation signals of filters or intersymbol interference); while multiplicative interference is caused by signals in wireless systems. multipath effects due to reflection, diffraction and scattering.
