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.
