Abstract: A transmitter for transmitting data in a communication system includes: a serial/parallel (S/P) conversion unit configured to convert data into an I signal and a Q signal; multiplication units configured to multiply the converted I and Q signals by orthogonal sequences, respectively; conversion units configured to Hilbert-transform the I and Q signals multiplied by the orthogonal sequences; addition units configured to add the I and Q signals multiplied by the orthogonal sequences and the Hilbert-transformed Q and I signal, respectively; and an intermediate frequency (IF)/radio frequency (RF) unit configured to up-convert the added I signal and the added Q signal and transmit the converted I and Q signals.

Abstract: An apparatus for transmitting data in a communication system includes: a processor configured to process broadcasting data regarding various types of digital broadcasts to be provided to users; an S/P converter configured to convert additional data of the broadcasting data into a parallel type; a phase selector configured to generate a phase selection value using additional data bits, except for a first additional data bit, of the converted parallel-type additional data; a sequence generator configured to generate a sequence using the first additional data bit and the phase selection value; and an adder configured to couple the generated sequence with the processed broadcasting data.
