CODER, RECEIVER, WIRELESS COMMUNICATION SYSTEM, PUNCTURE PATTERN SELECTION METHOD, AND PROGRAM THEREFOR

摘要

By controlling to select encoding appropriately considering characteristics of equalization and decoding of a receiving apparatus employing a turbo equalization technology, it is possible to attain a high transmission characteristic. Information bits of two systems including a sequence which is input to a first RSC encoding unit 22 and a sequence which is input through an interleaving unit 21 to a second RSC encoding unit 23 are set for input information bits, and each of which is subjected to RSC encoding. Each encoded parity bit is input to a puncturing unit 24. Since a systematic bit obtained by the first RSC encoding unit 22 is the information bit itself, a systematic bit obtained by the second RSC encoding unit 23 is not transmitted. In the puncturing unit 24, while puncturing is applied according to a predetermined coding rate, selection of either an RSC code or a turbo code is carried out by a puncturing control unit 25.
