Abstract
An apparatus and a method for preamble pseudo noise code allocation in a broadband wireless communication system are provided. The method includes defining an inherent index for each FA, allocating a preamble PN index to base stations using a reference FA index, defining an inherent offset by each FA for remaining FA indexes, and shifting the preamble PN index allocated to the base stations using the reference FA index by the defined offset, and allocating the preamble PN index to base stations using the remaining FA indexes. The price of a system can thus be lowered by reducing a Peak-to-Average Power Ratio (PAPR) of a preamble, increase the number of FAs that a specific amplifier can amplify, and immediately allocate a preamble PN index when adding a new FA during an operation of a system.
