摘要
The characteristics of the digital television terrestrial broadcasting (DTTB) channels with long impulse responses are analyzed, and the frequency domain multipath channel model is given. Based on single carrier and multicarrier these two different transmission modes, the cutoff rate expressions and the outage probability expressions of the DTTB transmission systems are derived. The performance of different DTTB standards-based or schemes-based transmission systems over DTTB multipath fading channels are compared both analytically and by computer simulations.
