Patent ID: 7545772

Claim:
A method for assigning subchannels in a wireless communication system, the method comprising the steps of: (1) generating (Q−1) subcarrier groups by classifying Q(Q−1) subcarrier bands; (2) detecting subcarrier bands corresponding to a sequence from Q subcarrier bands of each of the (Q−1) subcarrier groups; (3) assigning the detected subcarrier bands as a first subchannel; (4) interleaving the (Q−1) subcarrier groups and detecting subcarrier bands corresponding to an interleaved sequence from the Q subcarrier bands of each of the (Q−1) subcarrier groups; and (5) assigning the subcarrier bands detected from each of the interleaved (Q−1) subcarrier groups as a second subchannel; wherein the sequence is expressed as S 0 =α,α 2 ,α 3 , . . . ,α Q−2 ,α Q−1 , where S 0 denotes the sequence, Q denotes a size of a Galois Field, and α denotes a primitive element of a Galois Field (Q).
