摘要： Disclosed is a transmission device which transmits a systematic code obtained by adding parity bits to information bits. When the code rate of the systematic code is a value in a specific range determined by the decoding characteristic in a case where dummy bits are not inserted, a dummy bit insertion portion inserts dummy bits into the information bits and shifts the decoding characteristic, so that the code rate assumes a value outside a specific range determined by the decoding characteristic after shifting. An encoding portion performs systematic encoding of the information bits into which the dummy bits are inserted, and deletes the dummy bits from the results of the encoding to generate a systematic code, and a rate matching portion, performs rate matching such that the size of the systematic code is equal to a size determined by the physical channel transmission rate, and transmits the systematic code.

摘要： A receiver receives data transmitted from a transmitter. The data is stored in a buffer, and a reliability value of the data is computed by a computing unit. A determining unit determines reliability of the data by comparing a reliability value of existing data in the buffer and a reliability value of the data. When the reliability value of the data is higher than a predetermined value, the existing data is combined with the data. Then, an error correcting unit performs error correcting on combined data obtained, and outputs decoded bits. If the combined data includes many errors, retransmission of the data is requested to the transmitter. When the reliability value of the data is lower than the predetermined value, retransmission of data is directly requested without combining the data with the existing data.

摘要： 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.

摘要： 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.
