Apparatus and method for transmitting and receiving uplink sounding signal in broadband wireless communication system

An operating method of a receiving end for receiving an orthogonal sequence in a wireless communication system, the method comprising:

• generating a sequence corresponding to sequence allocation information of a transmitting end among a plurality of candidate sequences;
• receiving a signal string over a channel for carrying the orthogonal sequence from the transmitting end;
• and
• correlating the signal string with the generated sequence, wherein the sequence allocation information indicates a combination of at least one of a sequence length, a Zadoff-Chu sequence root index, orthogonal code indexes, and a cyclic shift offset, and
• the plurality of candidate sequences comprises sequences that are obtained by extending a product of a covering code comprising a plurality of orthogonal codes and a Zadoff-Chu sequence through cyclic shift and multiplying the extended product by a master covering sequence, the extending through the cyclic shift and the multiplying being performed before an Inverse Fast Fourier Transform (IFFT), and
• wherein the covering code comprises a first orthogonal code to enhance a correlation characteristic and a second orthogonal code to increase the number of the plurality of candidate sequences.
