Abstract: This paper discusses orthogonal frequency division multiplexing(OF-DM) as a channel coding scheme for terrestrial HDTV broadcasting. The pecfor-mance of OFDM in additive white Gauissian noise, multipath and co-cbannel interference environments is studied through computer simulation. Methods for reduction of the system's bit error rate are considered.

Key words: orthogonal frequency division multiplexing (OFDM), high defini-tion TV (HDTV), channel coding
