Abstract: A code bit of an LDPC code in which a code length is 16200 bits and an encoding rate is 8/15 is interchanged with a symbol bit of a symbol corresponding to any of 8 signal points defined by 8PSK. When 3 bits of code bits stored in three units of storages having a storage capacity of 16200/3 bits and read bit by bit from the units of storages are allocated to one symbol, a (#i+1)-th bit from a most significant bit of the 3 bits of code bits is set to a bit b#i, a (#i+1)-th bit from a most significant bit of 3 bits of symbol bits of the one symbol is set to a bit y#i, and a bit b0 is interchanged with a bit y1, a bit b1 is interchanged with a bit y0, and a bit b2 is interchanged with a bit y2.

Abstract translation: 码长为16200比特，编码率为8/15的LDPC码的码位与由8PSK定义的8个信号点中的任一个对应的符号的符号位进行交换。 当存储在存储容量为16200/3位并且从存储单元逐位读取的三个存储单元中的3位代码位被分配给一个符号时，从最多的（＃i + 1）位 3位码位的有效位被设置为位b＃i，来自一个符号的符号位的3位的最高有效位的（＃i + 1）位被设置为位y＃ i，并且位b0与位y1互换，位b1与位y0互换，位b2与位y2互换。
