본 논문은 다수의 단말이 다중 빔 위성을 통해 정보를 중심국으로 전송하는 위성 통신 시스템을 고려한다. 위성은 위상 배열 안테나를 탑재하여 서로 다른 대역폭을 가지는 다수의 스팟 빔을 형성한다. 빔 대역폭 할당의 공평성을 최대화하는 최적화 문제를 형성하고 해를 얻기 위한 두 가지 휴리스틱 알고리즘(반복적 빔 대역폭 할당, 자원 요청 비율 기반 빔 대역폭 할당)을 제안한다. 반복적 빔 대역폭 할당 알고리즘은 반복적으로 자원 요청량 대비 할당 대역폭의 비율을 균등화시키며, 자원 요청 비율 기반 빔 대역폭 할당 알고리즘은 요청량 대비 할당량 비율을 이용해 빔 대역폭을 계산한다. 모의실험을 통해서 반복적 빔 대역폭 할당 알고리즘이 최적의 해와 매우 가까운 공평성 성능을 가진다는 것을 확인하였다. 또한, 자원 요청 비율 기반 빔 대역폭 할당 알고리즘은 반복적 빔 대역폭 할당 알고리즘보다 계산 복잡도가 낮은 대신 더 낮은 공평성 성능을 가진다는 것을 확인하였다.
