Single Frequency Networks

In digital systems, alternative transmission scenarios with the utilization of distributed transmitters are possible and have been found to be efficient to improve signal coverage. One application of this idea is the Single Frequency Network (SFN), which uses distributed radio transmitters to broadcast the same signal over the same frequency channel. Coverage and reception improvement on shadowed areas are expected. This publication brings theory and results of field measurement carried out in a suburban SFN scenario with two synchronized transmitters.
