摘要： This invention proposes a transmission data generating apparatus for use in a transmitter of a communication system, which transmission data generating apparatus comprises a redundancy data obtaining unit for obtaining redundancy data of information data which was transmitted to a receiver and was not received successfully by the receiver; a new data obtaining unit, for extracting new data, which has not been transmitted to the receiver; and a combination unit, for combining the redundancy data and the new data to form a transmission data to be subsequently transmitted to the receiver. This invention enhances the success rate of decoding the new data in primarily transmitted data and retransmitted data, and enhances system throughput.
