PS-02 Analysis of Digital TV Quality Parameters (MER and BER) in Metropolitan Regions

This work describes methods for measure and characterize propagation channels for terrestrial Digital TV in Brazil, where the standard adopted is the ISDB-Tb. The measurements were made using a Drive Test to acquire the values of parameters that allowed the analysis of signal quality. Although the test performed allows the evaluation of several parameters, this work has been exposed to analyze only signal intensity, BER (Bit Error Rate) and MER (Modulation Error Rate). Also, it is presented evidences of the multipath phenomenon, which is one of the cause of deterioration of signal quality, and can be evaluated through the Drive Test.
