Geographic areas are divided into individual cells where cellular systems deliver wireless coverage. Available spectrum is partitioned into multiple channels with each cell allocated a channel set using Frequency Division Duplex (FDD). Frequency utilization occurs between cells with N cells forming a cluster, enabling inter-cluster frequency reuse. Key propagation characteristics (channel parameters) and co-channel cell locations are defined. Parameters include cell radius, path loss exponent, standard deviation of log-normal shadowing in decibels, base station transmit power level, mobile station transmit power level, number of sectors per cell, front-to-back ratio of sectorized antennas, number of instantaneous position groups for simulation, and co-channel interference threshold.
