Initial ranging process plays an important role in the mobile worldwide interoperability for microwave access (WiMAX) standard (IEEE 802.16e). Timing offset adjustment, power offset calculation and synchronization between the base station and all the users within a cell are achieved during the initial ranging process. A comparative study of existing and a novel ranging algorithm is proposed in this paper. Most of the current ranging algorithms do not take in to account the interference created by the ranging codes sent by other ranging users in an Orthogonal Frequency Division Multiple Access (OFDMA) setup [2][4][5][7]. The novel ranging method cancels the interference created due to the other raging codes in the ranging area. The simulation results indicate a significant improvement in performance under practical scenarios.
