Zusammenfassung:A method and an apparatus for transmitting a single-band orthogonal frequency division multiplexing (OFDM)-based ultra wideband (UWB) signal over a pipeline carrying a cable television broadcasting signal. The method includes transforming a multimedia signal transmitted from a multimedia device into a wireline UWB signal; transforming the wireline UWB signal into a single-band OFDM signal; and frequency-spreading the single-band OFDM signal according to a transmission rate. Thus, the apparatus can be robust to multi-path interference and extend transmission distance so as to increase transmission efficiency.
