    • A transmission device in a communication system where a systematic code obtained by systematic encoding of information bits into which dummy bits are inserted and by deletion of the dummy bits from the results of the systematic encoding is transmitted. The transmission device inserts dummy bits into information bits based on an interleaving pattern of an interleaving portion in a turbo encoder; performs systematic encoding of the information bits into which the dummy bits are inserted, and then deletes the dummy bits from the results of the systematic encoding to generate a systematic code; and transmits the systematic code. By considering the interleaving pattern, original bit positions, which, after interleaving, exists within the ranges of stipulated numbers of bits at the beginning and at the end, are determined in advance, and the dummy bit insertion portion executes control so as not to insert dummy bits into the original bit positions.

    • A method of transmitting data by transmitting apparatus, that includes controlling generation of bit sequences to adjust an occupation rate of systematic bits in a first data block including systematic bits and parity bits, which is obtained by encoding first data in a first encoding process, and is equal or closer to an occupation rate of systematic bits in a second data block including systematic bits and parity bits, which is obtained by encoding second data in a second encoding process, and to adjust an occupation rate of parity bits in the first data block that is closer to an occupation rate of parity bits in the second data block, in regard to first bit positions of the bit sequences generated using bits included in the first and second data blocks and performs multi-level modulation for transmission based on the generated bit sequences.

    • A method and apparatus operable to execute an error correction decoding process, while controlling the increase in the amount of data that is stored in the receiving apparatus, is disclosed. Data is preferably transmitted to a receiving apparatus to execute the error correction decoding process using received data and re-transmitted data. Transmitting data is generated by executing the rate matching process to a first part of the error correction coded data and generating a second transmitting data. The second transmitting data includes at least the data not included in the first part by executing the rate matching process. Also included is a transmitting means for executing the transmission of the second transmitting data as the re-transmission after the transmission of the first transmitting data.
    • 公开了一种在控制存储在接收装置中的数据量的增加的同时执行纠错解码处理的方法和装置。 优选地,将数据发送到接收装置,以使用接收的数据和重新发送的数据来执行纠错解码处理。 通过对纠错编码数据的第一部分执行速率匹配处理并产生第二发送数据来生成发送数据。 第二发送数据至少包括通过执行速率匹配处理而不包括在第一部分中的数据。 还包括发送装置,用于在发送第一发送数据之后执行第二发送数据的发送作为再发送。
