Preliminary Results of the Indoor Coverage Field Tests of the Advanced ISDB-T System in Brazil

This article presents the preliminary results of field tests with the Advanced Integrated Services Digital Broadcasting for Terrestrial Television Broadcasting (ISDB- T) system in indoor environments. Received channel power and error-free system reception threshold records were performed at four different measurement sites. Five different H/V dual-polarized MIMO antennas are used in measurements to evaluate system performance when using antennas from different manufacturers. The results show that the advanced ISDB-T system is robust to indoor penetration losses and when subjected to the use of different antennas.
