본 논문에서는 에너지 수확(EH) 회로가 비선형성을 보이는 MIMO(다중 입력 다중 출력) 간섭 채널을 통한 수확 전력 지향 SWIPT(동시 무선 정보 및 전력 전송) 방식을 연구합니다. 모든 수신기에서 수집된 전력을 최대화하기 위해 송신 빔 형성 벡터, 전력 분할(PS) 비율 및 수신 디코딩 벡터를 공동으로 최적화하는 알고리즘을 제안합니다. 모든 변수가 어느 정도 결합되어 있기 때문에 문제는 볼록하지 않고 해결하기 어렵습니다. 이러한 비볼록 문제를 해결하기 위해 반복 최적화 방법이 제안되었습니다. 두 변수가 고정되면 세 번째 변수가 최적화됩니다. 구체적으로, 송신 빔포밍 벡터가 최적화되면 전달된 목적 함수는 여러 분수 함수의 합이 됩니다. 비선형 비율 합 프로그래밍은 전달된 목적 함수를 해결하는 데 사용됩니다. 기존 EH 회로와 비교하여 제안된 방식의 수렴 및 이점은 시뮬레이션 결과를 통해 검증됩니다.

Abstract: This paper studies a harvested power-oriented simultaneous wireless information and power transfer (SWIPT) scheme over multiple-input multiple-output (MIMO) interference channels in which energy harvesting (EH) circuits exhibit nonlinearity. To maximize the power harvested by all receivers, we propose an algorithm to jointly optimize the transmit beamforming vectors, power splitting (PS) ratios and the receive decoding vectors. As all variables are coupled to some extent, the problem is non-convex and hard to solve. To deal with this non-convex problem, an iterative optimization method is proposed. When two variables are fixed, the third variable is optimized. Specifically, when the transmit beamforming vectors are optimized, the transferred objective function is the sum of several fractional functions. Non-linear sum-of-ratios programming is used to solve the transferred objective function. The convergence and advantage of our proposed scheme compared with traditional EH circuits are validated by simulation results.
