In this paper, the authors have proven mathematically that correlation of the shadowing component does not have any impact on the capacity of the Gaussian Cellular Multiple Access Channel under the global BS co-operation scheme. A system simulator that incorporates realistic distance dependent estimators for UT and BS shadowing correlation was also implemented and system capacity results were obtained. The simulation results confirm the theoretical analysis. They also provide actual values for the maximum achievable capacity of a real system employing a hyper-receiver.
