Coded OFDM With Transmitter Diversity for Digital Television Terrestrial Broadcasting (Corrected)*

摘要

This paper is a corrected version of that printed in IEEE Trans. Broadcast., vol.52, no3, p.325-35, 2006 September. Space-frequency coded (SFC) and channel coded orthogonal frequency-division multiplexing (COFDM) are considered under narrow-band interference (NBI). Analytical expressions for the bit error probability (BEP) are derived for OFDM with SFC in a frequency-selective fading environment. It is shown that SFC increases the resistance of COFDM against the NBI and reduces the BEP considerably. Specific attention is paid to Digital Terrestrial Television Broadcasting (DTTB), and the associated coding gains are discussed
