This paper analyzes the impact produced by the use of distributed MISO diversity techniques on the network planning for mobile broadcasting services, compared with the rest of variables considered in the design of these networks. In order to do that, we have evaluated the results obtained from the simulation of a wide variety of real cases of study, where different deployment topologies and different...
This paper studies two of the available heuristic algorithms to optimize the digital broadcasting network's planning. Particle Swarm Optimization (PSO) and Simulated Annealing (SA) are compared working in different OFDM modes. These algorithms manipulate the information of the network with static delays in order to maximize the covered area as well as possible at minimum cost. Particle Swarm Optimization...
This paper describes the location variability of the received field strength derived from the statistical analysis of data obtained during a set of tests carried out in the cities of Bilbao and Madrid. The systems and services referred in this study are those ones operating in UHF band, specifically in TV Bands IV and V (470 – 860 MHz). Their evaluation has been based on the empirical references of...
In this work, the usefulness and limitations of a planning tool that combines a propagation prediction method and a modern heuristic technique when applied to improve the coverage area in single frequency networks (SFN) is presented. The propagation prediction method uses 3D digital terrain maps along with a propagation model to estimate the contribution of any transmitter of the SFN at each location...
The digital broadcasting systems (DRM and HD radio/ IBOC) developed in the last decade have renewed the interest for the MW band. The planning requirements of the digital services require more accurate channel models and a significant improvement in the coverage estimation algorithms. The variability of the local median values (sigmaL) is a key parameter in the estimation process of the coverage percentage...
Some basic rules and values to include the attenuation effect of terrain obstacles in the medium wave (MW) band are presented. The analysis applies to ground wave propagated signals and focuses on the new digital broadcasting systems (HD-RADIO/IBOC and DRM) that require accurate predictions for appropriate network planning. This study is based on field strength data from a measurement campaign and...
