August 1994 | NTIA Technical Report TR-94-316
George A. Hufford
Abstract: "Orthogonal Frequency Division Multiplexing" is an interesting system architecture for high data-rate digital transmission that has been receiving renewed attention. This report is a discussion of how it works and of how it might be used to carry High Definition Television (HDTV). The principle tool is a computer simulation that allows us to look at many aspects of an OFDM system. It is concluded that the claims for the system largely hold up, and that its use might simplify many technical problems for HDTV.
Keywords: multipath; interference; spectrum efficiency; computer simulation; HDTV; OFDM; signal-to-noise
