Abstract

To improve the transmission performance of terrestrial digital multimedia/television broadcasting (DMB-T) system, the performance of an efficient space-frequency transmitter diversity scheme is introduced in this article. This scheme maintains the original transmitter branch and the network structure is simple to upgrade. DMB-T system is an important candidate for Chinese digital television terrestrial broadcasting (DTTB) standard. The system was simulated over both slow and fast fading DTTB channels. Simulation results show that the introduced transmitter diversity scheme can efficiently improve the system performance in fading environments
