APPARATUS AND METHOD FOR TRANSMITTING A SUB-CHANNEL SIGNAL IN A COMMUNICATION SYSTEM USING AN ORTHOGONAL FREQUENCY DIVISION MULTIPLE ACCESS SCHEME
摘要
<p num="1"><br/><br/><br/>A method of allocating sub-channel signal interleaving patterns to base <br/>stations (BSs) forming a wireless communication system capable of dividing a <br/>frequency band into a plurality of sub-carriers and including a plurality of <br/>sub-channels. The method comprises the steps of creating a basic orthogonal <br/>sequence having a length identical to a number of the sub-carriers forming the <br/>sub-channel; creating a plurality of sequences having lengths identical to the <br/>length of the basic orthogonal sequence by one of cyclic-shifting the basic <br/>orthogonal sequence and through performing a modulo operation based on a <br/>number of the sub-carriers forming the sub-channel, after adding a <br/>predetermined offset to the basic orthogonal sequence; selecting a <br/>predetermined number of sequences corresponding to a number of the BSs; and <br/>allocating the selected sequences as the sub-channel signal interleaving <br/>patterns for the BSs.<br/>
