Abstract

The power controlled IS-95 reverse-link is studied. It is observed that received signals from multiple links under soft handoff and power control arenot independent but anticorrelated, The cause of the anticorrelation is investigated through analysis and simulation. It is shown that due to this anticorrelation, the required signal-to-interference ratio (SIR) to achieve agiven frame error rate can be similar to0.7 dB less than previously estimated based on the independence assumption. Such an observation also leads toa more accurate reverse-link capacity estimate. Finally, it is pointed outthat by using a postselection power control configuration an additional rapacity increase of up to 11% is obtained.
