Introduction to FM Single Frequency Networks
Werner Drews Single Frequency Networks (SFNs) are a form of broadcast network design where several transmitters use the same frequency channel to send the same signal. SFNs are usually used for radio and digital TV broadcasting FM, AM and digital radio can be transmitted over SFNs while analog television is more problematic because the multiple signal sources tend to produce ghosting.
