摘要

A method of allocating sub-channel signal interleaving patterns to base stations (BSs) forming a wireless communication system capable of dividing a frequency band into a plurality of sub-carriers and including a plurality of subchannels. The method comprises the steps of creating a basic orthogonal sequence having a length identical to a number of the sub-carriers forming the sub-channel; creating a plurality of sequences having lengths identical to the length of the basic orthogonal sequence by one of cyclic-shifting the basic orthogonal sequence and through performing a modulo operation based on a number of the sub-carriers forming the sub-channel, after adding a predetermined offset to the basic orthogonal sequence; selecting a predetermined number of sequences corresponding to a number of the BSs; and allocating the selected sequences as the sub-channel signal interleaving patterns for the BSs.
