Comparativa entre los estándares de televisión digital ISDB-TB y DVB-T2 con canalización 6MHZ.

Abstract

The objective of this research work was to make a comparison between the ISDB-Tb and DVB- T2 Digital Television standards with 6MHz channeling, having as a precedent that our country welcomed ISDB-Tb television on March 26, 2010 as the appropriate standard, meanwhile in Colombia DVB-T2 is chosen, being the first time that this standard is used with 6Mhz of channeling, which is typical of Latin American countries, for which the comparative action was carried out in terms of performance, capacity and coverage of mentioned standards, through simulations in professional software and calculations in the AWGN, Rice and Rayleigh channels, and simulation of coverage with the ICS Telecom software, in addition, a comparative analysis of them was carried out in the transmission modes presented by each standard. In order to determine the performance of the two digital television standards and make a comparison between the values and determine which signal is more robust, the CNR calculation of ISDB-Tb and DVB-T2 was carried out. It was concluded that DVB-T2 is much more robust, has greater capacity and coverage unlike ISDB-Tb, this being an advantage when transmitting in real time, and improves the reception level of the signal. It is recommended to consider the robustness that DVB-T2 presents with respect to ISDB-Tb at the time of the deployment of DTT networks, so that an optimal service can be guaranteed on the border with Colombia, avoiding possible interferences.
