%%%  Abstract, in English

\begin{abstracten}%
The scope of this thesis was the development of a methodology in
order to detect, recognize and record signals in a certain
spectrum. This methodology was applied to the finding of
interferences into the spectrum of the cellular mobile
communications system DCS 1800 in the wider area of the Attika
basin. For that purpose, outdoor measurements were carried out at
selected sites. The processing of the measurements showed the
existence of interferences into the DCS 1800 spectrum.

Specifically, the DCS 1800 cellular system was studied and the
interference theory was presented. Furthermore, DCS 1800 signals
were generated at the laboratory with the use of a digital
generator and a laboratory test - extraction of the
characteristic curves - of passive (Bandpass Filter, co-axial
cables) and active elements (LNA) was carried out, using a HP
Network Analyzer. Moreover, the interferences were recorded on a
hard disk through a HP Spectrum Analyzer and proper software.

This methodology can be used as a guide for carrying out both
outdoor and indoor measurements in any spectrum, by making simple
changes at the function keys of the Spectrum Analyzer. The
usefulness of the methodology is the specification of the
procedure of the measurements in steps, from the protection of
the personnel and the equipment up to the analytical stages of
the measurements procedure.
