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 saving and very good power utilization. The SFN concept requires a new design methodology to take full…

An heuristic optimization approach using simulated annealing (SA) has been proposed and impact of additional frequency layers on LSA and global service area (GSA) coverage will be analyzed.
Reception Quality Prediction in a Single Frequency Network for the DTMB Standard
TLDR
A method featuring low complexity and low workload is proposed to estimate the reception quality under the SFN environment with the maximum delay spread of the artificial multipath no longer than the guard interval, supporting an unambiguous prediction of the signal-to-noise ratio (SNR) threshold according to the parameters of received signals.

Minimal cost coverage planning for single frequency networks
TLDR
This work focuses on the cost efficient design of an SFN providing broadcasting services over a predefined service area with requirements both on the received signal quality and on the allowable interference level experienced by existing services in the same spectrum.
On the outage probability in single frequency networks for digital broadcasting
TLDR
Results show that in wide-area networks, very low outage probabilities may be achieved with very modest transmitter powers, which implies that good network planning results in low-power, closely spaced transmitters.

TLDR
This paper provides a simple framework to estimate the correlation coefficient between the total useful and total interfering power, which is used as a correction factor in estimating the mean and standard deviation of the SIR, modeled by a lognormal distribution.
An advanced algorithm for improving DVB-T coverage in SFN
TLDR
The performance evaluation shows the significant coverage improvement offered by the gradual degradation CD3-OFDM algorithm, especially in the cases of omni-directional antennas, medium to high bit-rates and transmitter distances exceeding 40 km.
On the performance of single frequency networks in correlated shadow fading
TLDR
Results for both wide area and local SFN show that the coverage properties depends on the correlation in the shadow fading, which will affect the planning process since strong correlation, due to the structure of the terrain, yields better coverage for high transmitter powers (interference limited systems) and worse coverage for low transmitter power (noise limited systems).
Design of DAB/DVB Based Multimedia Radio Networks for Mixed Broadcasting and Personal Services
TLDR
This paper forms the network planning problem with this additional requirement as an optimization problem, where the objective is to minimize the network cost while satisfying both the capacity and the signal quality constraints and proposes an efficient heuristic algorithm that uses linear programming steps to iteratively build the network.
Outage probability in the presence of correlated lognormal useful and interfering components
TLDR
A simple method is proposed for estimating the correlation coefficient between the total useful and total interfering signals as the function of the correlation between the individual components and it is shown that considerable accuracy improvement can be achieved in the outage probability estimation.
