THE PERFORMANCE OF DVB-T2 SIGNAL NETWORK IN THE DRY SEASON
A Case Study of Jos in Nigeria
Keywords:
Propagation of DVB-T2 Signal, Field Measurement of Signal Parameters, Carrier to Noise Ratio (CNR) and Signal to Noise Ratio (SNR)Abstract
This study presents the performance of DVB-T2 Television network in Jos using Integrated Television Services Limited signal (NTA Signal Distribution Company). The perturbation arising from poor weather conditions remain a major problem to TV signal transmission in Nigeria due to signal attenuation and degradation between the transmitter and receiver station. These atmospheric perturbations are prevalent along the signal paths. This research aim is to evaluate the performance of DVB-T2 TV network in Jos, Plateau State. Drive test measurements methodology was adopted in measuring field strength and received signal strength parameters. These measured parameters were used to calculate for CNR and SNR through empirical method. Finally, CNR and SNR were used to evaluate the performance of DVB-T2 television network in Jos. The result of the research shows that DVB-T2 television network had a better signal quality (performance and coverage) in the dry season compared to the raining season.
