단일 중계기 채널에서의 협력 재전송 프로토콜

  • Published : 2011.07.30

Abstract

기존의 고정 중계를 하는 협력 통신 프로토콜은 중계기가 언제나 신호를 보내기 때문에 전송률이 높은 경우에는 비효율적이다[1]. 그러므로 수신단이 요구하는 경우에만 중계기가 신호를 송신하는 협력 재전송 프로토콜이 제안 되었다. 본고에서는 다양한 협력 재전송 프로토콜을 소개하고 송신단이 각 링크의 평균 신호대 잡음비만 아는 경우의 프로토콜들의 달성 가능 전송률을 비교한다. 또한, 전송 횟수에 제한이 없는 경우에 각 협력 재전송 프로토콜의 에르고딕 전송용량 달성 여부를 알아본다.
