ON DVB-H RADIO FREQUENCY PLANNING: : ADJUSTMENT OF A PROPAGATION MODEL THROUGH MEASUREMENT CAMPAIGN RESULTS
The present Master Thesis analyzes the DVB-H radio Frequency Network Planningproblematic, studying the influence of a propagation model used in the calculation ofnetwork coverage. In this way, the aim of this work is the design of a procedure andalgorithm to adjust a propagation model considering measurement campaigns performed indifferent environments (dense-urban, urban, sub-urban and rural).The methodology relies on the adjustment of the Xia-Bertoni propagation modelparameters using the Least Mean Square (LMS) method, considering the collectedmeasurements and the simulation model parameters obtained from a GeographicInformation System (GIS). Coverage simulations and measurement results are comparedusing a 3-Dimensional city model (terrain and buildings) for different terrain topologies(flat, hills and canyons) and environments.The resulting adjusted model has been tested and compared with other commonmodels (COST231 and Okumura-Hata) using specific metrics, thus proving its validity fordifferent frequencies, environments and terrain topologies. In order to validate theprocedure and designed algorithm, this Master Thesis gathers real data from measurementcampaigns carried out in different cities: Gävle (Sweden), Bucaramanga (Colombia),Valencia (Spain) and Munich (Germany). Besides, this work provides an insight on bestpractices to perform measurement campaigns.The outcome of this work is a useful tool in radio network planning for DVB-Hsystems, which ensures reliable results in all environments and terrain topologies.
