When successive interference cancellation (SIC) is employed, the mobile users with high signal-to-interference-plus-noise ratio (SINR) do not necessarily produce excessive multiple access interference as they do when single user detection is employed. Thus, in cellular CDMA systems employing SIC, there exists an alternative receiving power pattern other than the geometric receiving power pattern,...
In this paper, a novel approach to derive the mean, variance, and higher order central moments of reverse link inter-cell interference in cellular CDMA systems is proposed. As compared to previous research publications, this new approach does no put any restriction on the receiving power of mobile users, so it can be used to analyze the reverse link inter-cell interference not only for cellular CDMA...
Analytical expressions that allow one to analyze the total transmitted power in various cellular systems are important design tools in network optimization. This paper develops a new method of finding the total transmitted power by mobile stations (MSs) in systems with different power profiles and very general propagation conditions. Specifically, a closed-form expression is derived, based on the...
In this paper, the effects of imperfect power control on the reverse link outage probabilities of cellular CDMA systems employing successive interference cancellations (SIC) are thoroughly investigated. Both theoretical and computer simulation results show that the capacity of cellular CDMA systems employing SIC are very sensitive to imperfect power control. Hence, this is a large capacity gap between...
In this paper, under the constraint of finite maximum transmitting power the reverse link outage probability of cellular CDMA systems employing successive interference cancellation is analyzed. Moreover, the optimal average receiving power of mobile users is investigated to minimize the outage probability. Both theoretical analysis and computer simulations show that optimizing the average receiving...
This paper presents a new approach in analyzing the reverse link capacity performance of cellular CDMA systems employing successive interference cancellation (SIC). Due to the controlled power disparity present in such systems previous methods cannot precisely model their inter-cell interference. We first introduce a novel model which allows the accurate analysis and evaluation of the inter-cell interference...
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...
