초록

본논문을 통해, 리드솔로몬 복호기에서 매우 복잡한 나누기회로를 사용않고, 오류위치를 찾아내는 치엔기기의 최적설계기법을 제시했다. 최적화는 매우 간단한 제곱/4제곱회로를 사용하고, 병렬처리를 통해 가능했다. 이법은 현대 디지털 통신및/가전기기 대부분에 응용되질수 있다.

In this paper, we show new method to find the error locations of received Reed-Solomon code word. New design is much faster and has much simpler logic circuit than the former design method. This optimization was possible by very simplified square/$X^4$ calculating circuit, parallel processing and not using the very complex Divider. The Reed Solomon decoder using this new Chien Machine can be applicated for data protection of almost all digital communication and consumer electronic devices.
