<P>PROBLEM TO BE SOLVED: To obtain excellent reception quality, when creating an LDPC-CC from a convolution code, applying error correction encoding using the LDPC-CC to a signal series and transmitting the signal series. <P>SOLUTION: In the equation (1) which is a parity check polynomial of a convolution code when "1" is added to an approximation lower triangle matrix of a check matrix H (501, 502), α<SB POS="POST">1</SB>, ..., α<SB POS="POST">n</SB>and β<SB POS="POST">1</SB>, ... β<SB POS="POST">m</SB>are set to 2K+1 or more to obtain a parity series P(D) by the equation (1). <P>COPYRIGHT: (C)2013,JPO&INPIT |
