초록

다중 포인트 협력 통신 기술(CoMP; Coordinated Multi-Point)은 3GPP(3rd Generation Partnership Project)의 LTE-A(Long Term Evolution-Advanced) 시스템 기술 중 하나로 고려된다. 본 논문에서는 CoMP 기술의 세부 기법 중 하나인 CB(Coordinated Beamforming) 기법에 대하여 설계하고, 이를 바탕으로 성능 분석이 이루어졌다. LTE-A 시스템의 이종 네트워크(HetNet; Heterogeneous Network) 환경에서 몬테카를로 모의실험이 이루어졌으며, CDF(Cumulative Distribution Function) 그래프를 통하여 그 성능을 확인한다. 모의실험 결과를 통해 CoMP 기술을 사용하였을 때 성능 이득을 얻을 수 있으며, CoMP 기술에 다양한 스케줄링 및 프리코딩 기법을 적용하였을 때 더 좋은 성능을 가져오는 것을 확인할 수 있다.

Coordinated Multi-Point (CoMP) is considered as a technology in the 3rd Generation Partnership Project(3GPP) Long Term Evolution-Advanced (LTE-A) system. In this paper, we design and analyze the performance of the Coordinated Beamforming (CB) technique, which is one major category of CoMP. We perform Monte Carlo simulations with a Heterogeneous Network (HetNet) in LTE-A, and confirm the performance through a graph of the Cumulative Distribution Function (CDF). From the simulation results, we show significant performance gain with the CoMP technique, and better performance when we apply various schemes of scheduling and precoding.
