Abstract

In this paper, we propose a simple bidirectional transmission protocol using network coding and digital Fountain codes. In particular, in the proposed scheme, two sources use digital Fountain codes to transmit their message to each other with the help of relays. Then, relays use Fountain codes and network coding to forward the source messages to both sources. To evaluate performance of the proposed protocols, we present the average total throughput over Rayleigh fading channels via Various Monte-Carlo simulations. Results show that the proposed protocol outperforms the two-way relaying transmission protocol without using network coding technique at high SNR region.

본 논문에서는 네트워크 코딩 및 파운 테인 코드를 사용한 간단한 양방향 전송 프로토콜을 제안한다. 특히, 제안된 기법의 경우, 두 소스는 중계기의 도움으로 서로에게 메시지를 전송하기위해 디지털 파운틴 코드를 사용한다. 또한, 중계기는 파운틴 코드와 네트워크 코딩을 사용하여 수신 받은 소스의 메시지를 서로의 소스에게 전송한다. 제안된 프로토콜의 성능을 평가하기위해 레일리 페이딩 채널에서 다양한 몬테-카를로 시뮬레이션을 통하여 전체 평균 처리량을 확인한다. 그 결과 제안된 프로토콜은 높은 SNR 영역에서 네트워크 코딩 기술을 사용하지 않는 두 방향 릴레이 전송 프로토콜보다 우수함을 확인하였다.
