Interference Minimization in Wireless Communication Systems by Optimal Cell Site Selection
Kurt Tutschku, Rudolf Mathar, Thomas Niessen · 1999
: This paper presents two automatic cellular network design algorithms which determine the favourable positions of transmitters with respect to co-channel interference #CCI#. The proposed methods are capable of maximizing the average CCI ratio in the planning region while optimizing the covered teletra#c demand. Additionally,weinvestigate how the proposed algorithms can be extended for locating micro- and macro-cells. 1 Introduction The cellular concept introduces frequency reuse for FDMA#TDMA wireless networks to increase the tra#c capacity of the radio part of these systems. Users in geographically separated areas are simultaneously employing the same carrier frequency. However, the frequency reuse introduces co- and adjacent-channel interference which limits the theoretical capacity gain of the reuse if the geographical separation of cells with the same frequency is too small. The high capacity design of a cellular network requires that, after selecting the cell site, frequencies...
