Abstract

This paper proposes a power allocation method for multiple node beamforming with uniform circular array antennas to increase SIR of nodes in wireless mesh network. The proposed method calculates beamforming power allocation vectors that maximizes SIR satisfied with power constraint of HPA. The simulation results demonstrate the proposed method achieves the enhanced SIR of nodes than that of beamforming method.

본 논문에서는 원형 배열 안테나를 사용한 무선 메쉬 네트워크 LOS 환경에서 다중 노드 빔 형성을 위한 SIR 향상 빔 형성 전력 할당 기법을 제안한다. 제안된 방법은 다중 노드 접속을 위한 다중 노드 빔 형성 시 존재하는 전력 제한 조건을 만족시키며 송신 전력이 최대화되는 다중 빔 전력 할당 기법이다. 전산 모의 실험을 통하여 제안 한 빔 형성 전력 할당을 적용하였을 때 UCA 안테나에서 기존의 방법보다 다중 노드의 SIR이 향상됨을 확인하였다.
