Abstract: The present invention relates to a single carrier-based hybrid LDC system apparatus, comprising the following an LDC unit encoding at least one symbol including a CP using a hybrid LDC technique; a training sequence generation unit generating a training sequence with a CAZAC sequence encoded into a STBC; a transmission device including a frame unit for forming one transmission frame with a data stream encoded into symbols by the LDC unit and the CAZAC sequence encoded into the STBC by the training sequence generation unit; a separation unit separating the CAZAC sequence encoded into the STBC from the data stream of the transmission frame transmitted from the transmission device; a channel estimation unit estimating a channel from a frequency domain using the CAZAC sequence separated by the separation unit; and a reception device including a symbol recovery unit recovering the symbol encoded by the hybrid LDC technique using information on the channel estimated by the channel estimation unit. According to the present invention, the single carrier-based hybrid LDC system can transmit data at a transmission rate higher than that of an existing single carrier system, so can be adopted in a next generation broadcast system, or a 3DTV or UDTV broadcast system requiring a high transmission throughput.
