ATSC multipath channel characterization for fixed and mobile reception

For the investigation of the wireless channel for the Advanced Television Systems Committee (ATSC) Terrestrial Digital Television (DTV)multipath channel transmission system, channel characterization and modeling are very important for the system designer. Based on the channel estimation procedure, we present a data analysis of the distribution of the fixed and mobile DTV multipath channels in different environment. We analyzed the power delay profiles, distributions of the root mean square (RMS) delay spread, multipath number distributions and the arrival time distributions. The modified Poisson model has been applied to compare with the statistical model of the multipath for each channel.
