AN EXPERIMENTAL STUDY OF QUALITY ANALYSIS METHODS IN DVB-S/S2 SYSTEMS
Alexandru Florin Antone, Radu Arsinte
The paper is proposing a study and practical experiments of testing methods in digital television, transmitted in Digital Video Broadcasting standard. The main objective of the research presented in this paper was to establish if the testing tools designed and validated for DVB-S, are useable to evaluate DVB-S2. This is important in educational environments and small enterprises, to find new applications for the existing equipment. Testing methods follows three directions: transmitted services (data link layer), RF (Radio Frequency) interface and reception (physical layer). We pursued the following objectives: DVB-S2 model study (from Simulink Matlab), to establish the key measurement points in this evaluation, analysis of DVB-S/S2 streams, RF parameters measurements in terms of C/N (Carrier to Noise Ratio) and spectrum.
