<p>The present Master Thesis analyzes the DVB-H radio Frequency Network Planning</p><p>problematic, studying the influence of a propagation model used in the calculation of</p><p>network coverage. In this way, the aim of this work is the design of a procedure and</p><p>algorithm to adjust a propagation model considering measurement campaigns performed in</p><p>different environments (dense-urban, urban, sub-urban and rural).</p><p>The methodology relies on the adjustment of the Xia-Bertoni propagation model</p><p>parameters using the Least Mean Square (LMS) method, considering the collected</p><p>measurements and the simulation model parameters obtained from a Geographic</p><p>Information System (GIS). Coverage simulations and measurement results are compared</p><p>using a 3-Dimensional city model (terrain and buildings) for different terrain topologies</p><p>(flat, hills and canyons) and environments.</p><p>The resulting adjusted model has been tested and compared with other common</p><p>models (COST231 and Okumura-Hata) using specific metrics, thus proving its validity for</p><p>different frequencies, environments and terrain topologies. In order to validate the</p><p>procedure and designed algorithm, this Master Thesis gathers real data from measurement</p><p>campaigns carried out in different cities: Gävle (Sweden), Bucaramanga (Colombia),</p><p>Valencia (Spain) and Munich (Germany). Besides, this work provides an insight on best</p><p>practices to perform measurement campaigns.</p><p>The outcome of this work is a useful tool in radio network planning for DVB-H</p><p>systems, which ensures reliable results in all environments and terrain topologies.</p>
