Influence of transmission channel on DVB-T signal

The article briefly describes parameters of transmission channel and parameters of measuring the transmission and the sources of possible transmitting errors. In the first part, types of the transmission channels, the theoretic planning of the signal coverage and causes of simulating of ideal transmission channels are shown. The next part deals with the types of errors and the causes of errors in the transmission channel. This enumeration includes the computing of some error parameters. The last part of the article deals with a possible multi-path propagation of the digital television signal from transmitter to receiver There is briefly explained a prevention of multipath reception by using a guard interval.
