NTIA Report TR-94-316Orthogonal Frequency Division Multiplexing:
|
|
|
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: computer simulation; HDTV; interference; multipath; OFDM; signal-to-noise; spectrum efficiency |
