Patent number: 8234557Abstract: 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.Type: GrantFiled: January 9, 2012Date of Patent: July 31, 2012Assignee: Fujitsu LimitedInventors: Shunji Miyazaki, Kazuhisa Obuchi, Tetsuya Yano
