In terrestrial Digital TV (DTV) field tests, it is highly desirable to obtain the test site impulse response for channel estimation. The European standard for digital terrestrial transmission DVB-T has been designed for fixed, portable and mobile reception. A new channel characterization technique using frequency-domain pilot time-domain correlation (FPTC) method for DVB-T systems has recently been proposed by X. Wang. In this work, we developed a set of algorithms to estimate the DVB-T channel impulse response using the FPTC method. A set of laboratory and field measurements were carried out to validate the FPTC channel estimation method. The results of our tests confirmed that the FPTC method could be easily implemented in practice providing accurate estimates of the channel. Further work is done to implement the FPTC program to the ATSC, the American standard for DTV broadcasting, channel estimation, and compare the results from these two systems.
