| 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. |
