Abstract

In this paper, we design and analyze the performance of Coordinated Multi-Point (CoMP) techniques to the number of users for next-generation cellular systems. We perform Monte Carlo simulations with Long Term Evolution-Advanced (LTE-Advanced) and confirm the performance from the graph of the Cumulative Distribution Function (CDF). From simulation results, we show the significant performance gain when CoMP technique is used and also show better performance when we apply the various schemes additionally as scheduling and precoding.

본 논문에서는 차세대 셀룰러 시스템을 위한 사용자들 간 다중 포인트 협력 통신 (CoMP; Coordinated Multi-Point) 기법에 대하여 설계하고 이를 바탕으로 성능 분석이 이루어졌다. LTE-Advanced (Long Term Evolution-Advanced) 시스템에서 몬테카를로 모의실험이 이루어졌으며, CDF (Cumulative Distribution Function) 그래프를 통해 그 성능을 확인한다. CoMP를 사용하였을 때 성능이 향상되는 것을 확인하였으며, 스케줄링과 프리코딩 등 여러 기법을 추가로 적용하였을 때 더 좋은 결과를 얻는 것을 확인한다.
