Abstract
We propose a delay profile estimation method for Digital Terrestrial Television Broadcasting (DTTB) using Orthogonal Frequency Division Multiplexing (OFDM). The delay profile is conventionally estimated by the auto-correlation method; however, the conventional method calculates pseudo delay paths unnecessarily, as well as the actual delay path. In contrast, our method no longer calculates pseudo delay paths, because of the phases of the transfer function obtained from the magnitude of the transfer function by Hilbert transform. Another feature of the method is its independency from transmission formats (mode, modulation of subcarrier, etc.), since our estimation method requires only the magnitude spectrum like the conventional estimation method.
