Abstract

A major consideration in the design of cellular mobile radio systems is cochannel interference. The author reports the results of an extensive computer simulation study of the cochannel interference caused by imprecise antenna locations. Using the tenth percentile of the S/I (signal-to-interference) distribution of the mature system as a criterion, interference problems are investigated for various percentage tolerances (which determine tolerance circles around ideal locations) and spatial distributions (which determine actual antenna location inside the tolerance circles). It is shown that system performance is highly sensitive to large percentage tolerances in later stages of cell splitting
