Abstract

In this paper, we propose a construction method of irregular quasi-cyclic low-density parity-check codes based on perfect difference families with various block sizes. The proposed codes have advantages in that they support various values with respect to code rate, length, and degree distribution. Also, this construction enables very short lengths which are usually difficult to be achieved by a random construction. We verify via simulations the error-correcting performance of the proposed codes.

본 논문에서 다양한 블록 크기를 가지는 완전 차집합군을 이용하여 불규칙 준순환 패리티 체크 부호를 생성하는 방법을 제안한다. 제안하는 부호는 기존의 설계방법들에 비해 부호율, 부호 길이, 차수 분포 측면에서 다양한 값들을 가질 수 있다는 장점을 보인다. 또한 랜덤한 방법으로 설계하기 힘든 매우 짧은 길이의 부호를 체계적으로 설계할 수 있다. 모의실험을 통해 제안하는 부호의 오류 정정 성능을 검증한다.
