The term is often used to refer to the addition of unwanted signals to a useful signal. Common examples are: In electronic communications, especially in telecommunications, an interference is that which modifies a signal in a disruptive manner, as it travels along a channel between its source and receiver. The term is often used to refer to the addition of unwanted signals to a useful signal. Common examples are: Interference is typically but not always distinguished from noise, for example white thermal noise. Radio resource management aims at reducing and controlling the co-channel and adjacent-channel interference.
