Mobile Reception of Digital Terrestrial Television Broadcasting : A study on equalizing method for muiti-path fading and Doppler shift using complex delay profiles

Abstract

We have been studying Digital Terrestrial Television Broadcasting with OFDM method. In this paper, we propose an equalizing method for muiti-path fading and Doppler shift. It used in front of FFT demodulator.At first, it gets complex delay profiles by any pilot symbols and then Dappler shift analyzed by GHA (Generalized Harmonic Analysis) method with complex delay profiles.
