Abstract

In this paper, we propose a new EIM(erasure insertion method) based on the average-minimal-noise-power for HOM(higher order modulation) over AWGN(additive white Gaussian noise) under PBJ(partial-band jamming). Then we design SFH/SS(slow-frequency-hopping spread-spectrum) system by applying this method and formulate the PER(packet error rate) of the system. Based on this formula, we propose a new method to set the optimal threshold of the EIM and verify it at the designed 16-QAM SFH/SS system.

본 논문은 부분 대역 재밍(partial-band jamming, PBJ)과 가산성 백색 가우시안 잡음(additive white Gaussian noise, AWGN)이 존재하는 채널에서 주파수 고효율 변조(higher order modulation, HOM)에 적용 가능한 평균 최소 잡음 전력 기반 소실 삽입 기법(erasure insertion method, EIM)을 제안한다. 제안한 기법을 적용한 저속 주파수 도약 대역 확산(slow-frequency-hopping spread-spectrum, SFH/SS) 통신 시스템을 설계하고, 이 시스템의 패킷오류율(packet error rate, PER) 계산식을 유도한다. 이를 바탕으로 주어진 시스템 사양에서 최적의 성능을 보이는 소실 삽입 판정의 잡음 임계값을 구하는 방법을 제시하고 설계한 16-QAM SFH/SS 시스템에서 이를 검증한다.
