In this paper, a path-loss-based successive interference cancellation (SIC), which successively decodes mobile users assigned to the same cell from the one with minimum path loss to the one with the maximum path loss and removes their contribution from the received signals in the same sequence, is proposed to reduce both the outage probability and the inter-cell interference of cellular CDMA systems. Without excluding the effects of lognormal shadowing fading and for an arbitrary cluster of homogenous hexagonal cells, we have theoretically analyzed the reverse link capacity improvement brought by the path-loss-based SIC over a conventional matched filter. Furthermore, by taking a pedestrian application in cdma2000 as an example, computer simulations are performed, and the obtained simulation results have perfectly confirmed our theoretical analysis.
