Abstract
Linear microcells employing low base stationantennas have been proposed for emerging PCS systems. Insuch systems, the characteristics of the propagation online-of-sight (LOS) radio links will fundamentally determine the system performance. In thiscontext, it is meaningful to discuss the effect onsystem design of the two commonly used propagationmodels, the two-slope model and the single-slope model.In this paper we present several methods tocompare the frequency reuse pattern and base stationseparation based on these two propagation models, andverify the importance of correct propagation modeling for efficient system design. We considerinterfering signals coming from two cochannel basestations in the first tier, and include slow fading losswhen comparing system performances. Based on systemdesign results and subsequent performance, thetwo-slope model is recommended for LOS PCSmicrocells.
