Abstract :
Multistage interference cancellers (MICs) have been studied extensively for increasing the cell capacity of the next generation wideband DS-CDMA cellular systems. However, most of previous works have assumed a single cell case and there have been little evaluation of the performance in multi-cell environments, which is degraded by the other-cell user interference because it cannot be cancelled by MICs. In this paper, we construct a simulation model of multi-cell environments based on theoretical analysis and evaluate the interference suppression factor, bit error rate and capacity gain of the MIC
