Abstract
A digital transmission system is provided. The system includes a transmission signal generation unit which generates transmission signals by loading data to be transmitted on carrier waves; and an additional data processing unit which loads a low power signal expressing additional data on the carrier waves on which the data is loaded by the transmission signal generation unit. The system may be embodied as an orthogonal frequency division multiplexing (OFDM) system such as a Digital Video Broadcasting-Terrestrial (DVB-T) system, or a single carrier system such as a Vestigial Sideband (VSB) system.
