ON DVB-H RADIO FREQUENCY PLANNING:: ADJUSTMENT OF A PROPAGATION MODEL THROUGH MEASUREMENT CAMPAIGN RESULTS

Abstract [en]

The present Master Thesis analyzes the DVB-H radio Frequency Network Planning

problematic, studying the influence of a propagation model used in the calculation of

network coverage. In this way, the aim of this work is the design of a procedure and

algorithm to adjust a propagation model considering measurement campaigns performed in

different environments (dense-urban, urban, sub-urban and rural).

The methodology relies on the adjustment of the Xia-Bertoni propagation model

parameters using the Least Mean Square (LMS) method, considering the collected

measurements and the simulation model parameters obtained from a Geographic

Information System (GIS). Coverage simulations and measurement results are compared

using 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 common

models (COST231 and Okumura-Hata) using specific metrics, thus proving its validity for

different frequencies, environments and terrain topologies. In order to validate the

procedure and designed algorithm, this Master Thesis gathers real data from measurement

campaigns carried out in different cities: Gävle (Sweden), Bucaramanga (Colombia),

Valencia (Spain) and Munich (Germany). Besides, this work provides an insight on best

practices to perform measurement campaigns.

The outcome of this work is a useful tool in radio network planning for DVB-H

systems, which ensures reliable results in all environments and terrain topologies.
