Resumo
This research presents a comparative study between the ISDB - TB and the second
generation of European standard DVB - T2 systems. As a case of study it is demonstrating
the information construction technique from the multiplexer system to the signal
construction stage for both systems. The ISDB -TB system presents diferent blocks and
processing techniques when compared to DVB - T2. On the other hand, these structures
have the same principle and can be divided into four stages named source encoding, channel
coding, modulation and transmission which are valid for both systems. The diferences
and similarities since BTS data entrance to ISDB - TB as well T2-MI to DVB - T2, up
to base band generation are presented. The measurements were performed in laboratory
and TOV (Threshold of Visibility) criterion was used to analyse both systems performances.
Emulations for performance analysis occurred in a channel on the interference
(sensibility) absence and in a noisy channel. The noises considered in the experiments
were white noise, impulsive noise, multipath and multiple-echoes. These measurements
were applied to both studies patterns. The final part of this work presents both systems
performance.
