Reverse link inter-cell interference analysis for cellular CDMA systems with random power disparity

Abstract

The existing reverse link inter-cell interference models for cellular CDMA systems are based upon the assumption that all mobile users have equal receiving power or controlled power disparity at the base stations they are assigned to. However, because of imperfect power control and/or the application of new signal processing techniques, in most case the receiving power demonstrates random disparity. In this paper, a novel inter-cell interference analysis approach is proposed, which can be applied not only in cellular CDMA systems with random power disparity, but also in those with equal receiving power or controlled power disparity.
