Interference consists of additional signals originating from sources other than the primary transmitter, which can disrupt the reception of the primary signal if their intensity exceeds a certain threshold. This threshold is determined by the channel through which the interference is received relative to the primary signal channel, as well as by the specific characteristics of the receiver used. The most common types of interference are those that overlap with the primary signal on the same channel (co-channel interference) and those that interfere from adjacent channels (adjacent-channel interference).
