Single Frequency Networks (SFN) in Digital Terrestrial Broadcasting

The paper deals with principles and properties of single frequency networks of digital television and radio transmitters. Basic definitions and contextual relationships (guard interval, area of SFN, influence of used modulation parameters etc.) are explained.

Single Frequency Network Planning

Both Digital Audio Broadcasting (DAB) and Digital Video Broadcasting (DVB) systems use orthogonal frequency division multiplexing (OFDM) to facilitate single frequency networks (SFNs). In an SFN all transmitters transmit the same information in the same frequency block simultaneously. This transmitter diversity structure makes SFNs very efficient in fading channels with an excellent spectrum sa...

Single Frequency Networks in Digital Radio

Not too surprisingly, a Digital Radio Single Frequency Network (SFN) shares the same properties as a Digital Television SFN. For this reason some of this paper has been taken from [1]. The main differences between radio and TV SFN are due to the different S/N requirements and guard intervals. SFNs do offer significant potential advantages including better coverage, less interference, less power...

Single Quadrant Digital Waveform Frequency Synthesis

This paper present a new technique in digital waveform synthesizers based on the use of the first quadrant in order to present the other three quarters. This will reduce the size of the memory locations to the quarter, and increase the number of samples per period four times in comparison with the full wave synthesizer.
