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, 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...
