Abstract

In this paper, a new method for finding optimal and short span in Convolutional Self-Doubly Orthogonal(CDO) codes are proposed. This new algorithm based on Parallel Implicitly-Exhaustive search, where we applied dynamic search space reduction methods in order to reduce computational time for finding Optimal Span for R=1/2 rate CDO codes. The simulation results shows that speedup and error correction performance of the new algorithm is better.

본 논문에서는 길쌈 Doubly 직교 부호의 최적 스팬을 찾기 위한 새로운 방법(Convolutional Self-Doubly Orthogonal, CDO)을 제안한다. 이 새로운 방법은 병렬 Implicitly-Exhaustive 탐색방법을 사용하는데, 이 방법으로 R =1/2 CDO 코드에 대한 최적의 스팬을 찾기 위해서 계산시간을 감소시키는 방법으로 동적 검색 공간 감소 방법을 적용했다. 제안된 알고리듬을 모의실험한 결과 기존의 방법에 비해서 계산시간이 감소되었고, 오류 정정 성능이 향상되었음을 확인하였다.
