Abstract :
In the cyclic delay diversity (CDD), the concept of cyclic delay is used for increasing system performance of OFDM systems under the flat-fading channel. In contrast with CDD, this paper suggests a supplementary data transmission scheme using the concept of cyclic delay (STCD) to transmit additional data bits without the additional system BW or antennas.
