Abstract

In this paper, we analyze the outage probability of macro diversity combining in cellular networks in consideration of aggregate interference from other mobile stations (MSs). Different from existing works analyzing the outage probability of macro diversity combining, we focus on a diversity gain attained by selecting a base station (BS) subject to relatively low aggregate interference. In our model, MSs are randomly located according to a Poisson point process. The outage probability is analyzed by approximating the multivariate distribution of aggregate interferences on multiple BSs by a multivariate lognormal distribution.

본 논문에서는 다른 모바일 단말에서의 통합적 간섭을 고려하여 셀룰러 네트워크에서 매크로 다이버시티 결합을 사용하였을 경우의 Outage 확률을 분석한다. Outage 확률을 분석한 타 논문과 달리 본 논문에서는 상대적으로 간섭이 적은 기지국을 선택하였을 때의 다이버시티 이득을 분석한다. 분석을 위해 모바일 단말이 포아송 포인트 프로세스에 따라 확률적으로 분포한다고 가정하였다. 다수의 기지국에 가해지는 통합적 간섭의 다변수 분포를 다변수 로그노멀 분포로 근사시켜 분석을 수행하였다.
