Abstract
A frequency selective digital transmission apparatus includes: a preamble transmission processing unit generating a preamble for frame synchronization and spreading the generated preamble with a predetermined spreading code; a header transmission processing unit configuring a header including data attribute information and spreading the header with a predetermined spreading code; a data transmission processing unit performing serial-to-parallel conversion on transmission data according to a selected transmission mode and a spreading scheme and spreading the same with a frequency selective spreading code; and a multiplexing unit multiplexing the preamble, the header, and the data which have been spread by the preamble transmission processing unit, the header transmission processing unit and the data transmission processing unit, respectively, and transmitting the same as digital signals.
