이 편지에서는 정전 가능성을 최소화하는 것을 목표로 하는 AF(증폭 및 전달) 기회주의적 중계 시스템에 대한 전력 할당 방법이 고안되었습니다. 먼저, 정전 확률에 대한 결과를 확장하고 전력 할당 문제를 단순화하기 위한 근사식을 개발합니다. 해당 최적화 문제가 구성되고 볼록형임이 입증되었습니다. 그런 다음 최적의 전력 할당 요소를 찾기 위해 반복적인 수치 방법이 제안됩니다. 또한 계산 복잡도를 줄이기 위해 전력 할당 요소를 직접 계산할 수 있는 최적에 가까운 방법을 제안합니다. 수치 결과는 제안한 방법이 이상적인 방법과 유사한 성능을 가지며, 적은 오버헤드로 동일한 전력 할당보다 훨씬 뛰어난 성능을 보인다는 것을 보여줍니다.

Abstract: In this letter, power allocation methods are devised for Amplify-and-Forward (AF) opportunistic relaying systems aiming at minimizing the outage probability. First, we extend the result on outage probability in and develop an approximate expression to simplify the power allocation problem. A corresponding optimization problem is constructed and proved to be convex. Then an iterative numerical method is proposed to find the optimal power allocation factor. We also propose a near-optimal method which can directly calculate the power allocation factor to reduce computational complexity. Numerical results show that the proposed methods have a similar performance with the ideal one, and outperform equal power allocation significantly with little overhead.
