Apparatus and method for transmitting sub-channel signal in a communication system using orthogonal frequency division multiple access scheme

The present invention divides a frequency band into a plurality of subcarriers, in a wireless communication system having a plurality of a set of sub-channels of the sub-carriers adjacent to the predetermined number, the same length as the number of subcarriers included in the subchannel and then generates a basic orthogonal sequence, after the basic orthogonal sequence a predetermined number of times one cyclic shift generating a plurality of sequences having a length equal to the basic orthogonal sequence by applying an offset set in advance, the number of having by selecting a sequence of the same number as the number of the base station of the sequence, and assigning the selected sequence, each of the base station of each of the sub-channel signal interleaving pattern is to distinguish the sub-channel consists of the adjacent subcarriers by the base station . Inter-cell interference, the sub-channel signal interleaving pattern, the Reed Solomon sequence, the orthogonal sequence, subcarrier collision characteristics
