TL;DRAbstract

The aim of this work is to study the performance of the European Terrestrial Digital TV system DVB-T, when improved with Time Interleaver similar to Japanese Terrestrial Digital TV System. We contribute with the development of a simulator named (DVBM-T) DVB Modified -T. To test the DVBM-T, two proposals of Channel Estimators (2D jointed with Cubic-Spline and 1D with Piecewice) were tested. The simulation tests were made in Channels with Impulsive Noise, Multipath, Doppler, White Gaussian Noise and others typical broadcast channels for Digital TV tests in Brazil. In this work, comparation between domestic receivers DVB-T and ISDB-T with the Modified DVB-T is also showed. The results achieved are presented and discussed.
