Abstract

The Line Code is a code used for data transmission and is a coding method used to prevent loss of data between transmitter and receiver. There are various kinds of line code such as B3ZS, HDB3, B8ZS, and HDB3 code is used in the tactical communication networks of Korea. In this paper, we implement the HDB3 Codec that is used in tactical communication networks in order to eliminate the risk factors for component discontinuance and to shorten development period and ensure reliability. Also it is confirmed that it can be implement by minimizing the amount of logic usage so that it can be used unrestrictedly in systems using FPGA and the implemented HDB3 Codec is simulated to confirm that it is equivalent to the performance of HDB3 Codec IC.

Line Code는 데이터 전송을 위해 사용하는 Code로 송수신기 간 데이터의 손실을 방지하기 위해 사용되는 데이터의 부호방식이다. Line Code의 종류는 B3ZS, HDB3, B8ZS 등 다양한 방식이 있으며 우리나라 군 전술통신망에서는 HDB3 Code를 사용하고 있다. 본 논문에서는 군 전술통신망에서 사용되는 HDB3 Codec을 로직으로 구현하여 단종에 대한 위험요소를 제거하고, 개발기간의 단축과 신뢰성 보장이 가능하도록 한다. 또한 최소한의 로직을 사용하여 HDB3 Codec 구현함으로서 FPGA를 사용하여 개발이 가능함을 확인하고 시뮬레이션을 통해 구현된 HDB3 Codec과 상용의 HDB3 Codec IC의 비교를 통해 하여 성능을 입증한다.
