Implications of power control and successive interference cancellation on indoor DS-CDMA system deployment and performance

Abstract

We investigate the optimal combination of power control and successive interference cancellation to yield performance gains in a multi-floor indoor DS-CDMA system. Using measured indoor propagation data and a Monte Carlo simulation, it is shown that the performance gains achieved are significantly influenced by the base station deployment strategy chosen.

Multiuser multirate DS-CDMA detection techniques in multipath fading channels

“…Most of the multiuser receivers mentioned earlier aim at providing better detection capabilities by combating MAI and the near-far effect. Power control is another technique to combat the near-far effect th at is used in practical DS-CDMA systems employing the conventional single user matched filter (or correlator) detector [87,88]. Power control consists of regulating the transm itting powers of mobiles users so th at the base station receives their signals with approximately the same mean power [87,89].…”

Various power control algorithms have been proposed in the literature (see for example [90]).…”
