Transport Stream Files Assembling and Analysis of BER Performance into ISDB-Tb Standard
This work presents a technique for assembling a TS (Transport Stream) file, in accordance with the ISDB-Tb (Integrated Digital Terrestrial Digital Transmission Services) standard, in order to transmit it through a digital TV signal generator to analyze the parameters variation effects of the ISDB-Tb system in the BER (Bit Error Rate) performance. For this analysis, measurements were taken in three different communication channels, with distinct features. In each channel the 16QAM and 64QAM modulations were evaluated, and several combinations were tested between the following parameters: operating mode, code rate, guard interval and time interleaving. Also, BER measurements were taken for a C/N (Carrier to Noise) range, set from transmitter, then it was calculated the Eb/No ratio, which allowed to plot curves for each measure.
