EUROFIX 시스템에 적용하기 위한 Reed-Solomon 부호 설계

Abstract

The function of the channel encoder is to introduce, in a controlled manner, some redundancy in the binary information sequence at the receiver. It is also required that the channel encoder can overcome the effects of noise and interference encountered in the transmission of the signal through the channel.

Thus, the added redundancy serves to increase the reliability of the received data and improves the fidelity of the received signal. In effect, redundancy in the information sequence aids the receiver in decoding the desired information sequence.

In this thesis, the Reed-Solomon code was designed, which is used in an EUROFIX system. The EUROFIX system uses the Loran-C system for information transmission.

As a result, this thesis proposed a design and implementation method of the (14, 9) RS encoder. In the decoder, the Galois Field Fourier Transform method was adopted for reducing the decoding time.

It is concluded that the decoding time get shorter clock times than a conventional method by the proposed one.
