Abstract  Abstract

QCTC (complementary code) generation device comprises: a fast encoder for the encoding sequence of information symbols to generate the information symbol sequence and a plurality of parity symbol sequences by channel interleaver generating new parity symbol sequence for respectively interleaving the information symbol sequence and the parity symbol sequences by multiplexing have the same priority of the parity symbol sequence of symbols and successive link information symbol sequence and the new parity symbol sequence and a QCTC generator for a given start position circularly selecting a predetermined number of symbols from the symbol sequence of link generating sub-code with a given code rate.

A QCTC (Quasi-Complementary Turbo Code) generating apparatus having: a turbo encoder for generating an information symbol sequence and a plurality of parity symbol sequences by encoding the information symbol sequence; a channel interleaver for individually interleaving the symbol sequences generating new parity symbol sequences by multiplexing the symbols of parity symbol sequences with the same priority levels and serially concatenating the information symbol sequence and the new parity symbol sequences; and a QCTC generator for generating a sub-code with a given code rate by recursively selecting a predetermined number of symbols from the concatenated symbol sequence at a given starting position.
