Abstract  Abstract

A Quasi-Complementary Turbo Code (QCTC) generating apparatus comprises a turbo encoder 201 for generating an information symbol sequence X and a plurality of parity symbol sequences Y0 Y1 Y0 and Y1 a channel interleaver 204 214 224 234 244 for individually interleaving the sequences multiplexers 205 215 for generating new parity symbol sequences by multiplexing parity symbol sequences with the same priority levels a symbol concatenator 207 for serially concatenating the information and new parity symbol sequences a repeater 208 for repeating the concatenated sequence and a puncturer 209 for selecting a predetermined number of symbols from the repeated sequence according to the code rate. The sub-codes enable optimum code combining at a receiver. Application is to hybrid automatic repeat request (H-ARQ) retransmission systems.
