Abstract :
In this paper, we study the quality of the terrestrial digital video broadcasting (DVB-T) transmission over the cable TV network. Usually, when terrestrial digital TV signals are distributed in the cable TV network a conversion is needed in the head-end, from DVB-T (OFDM) to DVB-C (single carrier). In this work we study the possibility of using the DVB-T signal without any conversion. At first, a simple model for the channel is designed taking into account the main impairments. Secondly, the performance of the DVB-T signal is simulated and compared to that of digital cable TV standard DVB-C that is based on single carrier technique. The comparison is based on the bit error ratio that each system can achieve, in the same channel environment. Channel interference problems are also simulated
