Apparatus and method for transmitting/receiving signal in communication system supporting bit-interleaved coded modulation with iterative decoding scheme반복 디코딩 방식으로 비트-인터리브 코드 변조 장치를 지지하는 통신 시스템에 있는 전송/수신 신호를 위한 장치와 방법
The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as a long term evolution (LTE). A method for transmitting a signal in a signal transmitting apparatus in a communication system supporting a bit-interleaved coded modulation with iterative decoding (BICM-ID) scheme is provided. The method includes performing an outer encoding operation; performing an interleaving operation on the outer code corresponding to an interleaving scheme which is based on a preset generation matrix to generate an interleaved signal; performing an inner encoding operation; performing a modulating operation; and transmitting the modulated signal, wherein the generation matrix is generated by applying at least one of a preset column permutation rule and a preset row permutation rule to a generation matrix for a quasi-cyclic (QC) interleaver.
