Abstract

In most digital communication systems over the noisy channel, some form of forward error correction scheme is employed for reliable communications. If one wants to recover the transmitted message without any knowledge of the error correcting codes employed, it is of utmost importance to figure out and reconstruct the error correcting codes. In this paper, we propose two algorithms of reconstructing linear cyclic codes from the corrupted received bit sequence, one for general linear binary cyclic codes and the other for Reed-Solomon codes. For two algorithms, we ran computer simulations and the performances are shown to be superior to those with the conventional LWM method.

잡음에 있는 채널을 통한 디지털 통신에서는 채널 잡음에 대항하기 위해 오류정정부호(채널부호)를 사용하게 된다. 만일 송신측의 협조 없이 전송정보를 알아내려면 사용된 채널부호를 복원하는 것이 무엇보다 중요하다. 본 논문에서는 잡음에 오염된 수신 비트열로부터 사용된 채널부호의 여려 파라메타를 추출하여 궁극적으로 채널부호를 복원하는 채널부호 복원기법 중 순회부호(cyclic code)의 복원 기법을 제안한다.
