Abstract

In this letter, we compare the performance of two concatenated coding structures in slow FH/SS systems for multimedia/multicast transmission on shipboard. Two outer code symbols are transmitted during a hop. The first structure consists of one inner codeword per one outer code symbol, while the second structure consists of one inner codeword per two outer code symbols. We analyze the overall block error probability in asymptotic region and show that the performance of the second scheme is superior to the first one.

본 논문은 해상환경에서 느린 주파수도약 대역확산 통신을 이용하여 멀티미디어/멀티캐스트 데이터를 전송할 때 사용하는 쇄상부호의 두 가지 내부호 구조에 따른 성능을 비교, 분석하였다. 첫 번째 내부호 구조로는 한 외부호 심볼당 하나의 내부호를 사용하는 것이고, 두 번째 내부호 구조로는 두 외부호당 하나의 내부호를 사용하는 것을 고려하였다. 점근적인 수학적 해석을 통하여 후자의 경우가 전자보다 더 성능이 우수함을 확인하였다.
