On the outage probability of MBSFN in correlated shadow fading

In traditional analysis to the performance of MBSFN uncorrelated shadow fading is used. In some cases this assumption does not capture the behaviors of the shadow fading. In this paper, a novel analytical model of system, user equipment receiver and correlated shadow are proposed firstly, then the performance measures were introduced, the changes in coverage due to correlation among the received signal from different eNBs was investigated. Numerical results demonstrate that the coverage properties depend on the correlation in the shadow fading due to the structure of the terrain. Moreover, strong shadow correlation yields better coverage for high transmission power. It is helpful for MBSFN planning by using this model.
