Abstract

본 발명에 의한 길쌈 부호기/복호기는 기존의 길쌈 부호기/복호기에 계통적 길쌈 부호기/복호기를 병렬로 연결하여 구현한 것으로서, 두 개의 계통적, 비계통적 길쌈 복호기의 결과를 추정된 신호대 잡음을 이용하여 하나의 결과를 선택하게 함으로써 채널의 변화가 심한 시스템에서도 항상 좋은 수신을 할 수 있게 한 것이다.The convolutional encoder / decoder according to the present invention is implemented by connecting a conventional convolutional encoder / decoder to a conventional convolutional encoder / decoder in parallel. Selecting the result ensures good reception at all times, even in systems with fluctuating channels.
