Patent Number: 8,719,679

Title: Transmission apparatus reception apparatus and communication system

Abstract: To improve performance of a decoder even in a system with the coder configuration determined by inserting a doping bit sequence known between a transmission apparatus and a reception apparatus in an information bit sequence to transmit, the transmission apparatus is a transmission apparatus that transmits radio signals to the reception apparatus, and is provided with a doping section 23 that inserts a doping bit sequence which is known between the transmission apparatus and the reception apparatus in an information bit sequence to transmit to the reception apparatus, coding sections 11a, 11b that perform error-correcting coding on a bit sequence with the doping bit sequence inserted therein, a puncturing section that performs puncturing on a bit sequence subjected to the error-correcting coding, and a wireless transmission section 24 that transmits a bit sequence subjected to the puncturing.
