Abstract
Out-of-cell interference is an important factorin determining the system capacity of CDMA systems.Out-of-cell interference is influenced by propagationparameters such as slope index s of the path loss model, the standard deviation sigma of shadowloss, and the correlation coefficients of shadow lossfor propagation from the desired base station and fromthe interfering base station. For line-of-sight (LOS) cells along streets or roadways,propagation may be described by a two-slope model thathas smaller slow-fading loss sigma and a larger slopeindex past the breakpoint Rb than thesingle-slope model. As a result, smaller out-of-cellinterference is obtained with the two-slope model,leading to system designs having less infrastructurethan are obtained using the single-slope model. In thispaper we examine how a more realistic prediction ofquality of service (QOS) made with the two-slope modelleads to cost-effective system designs.
