The algorithm of one-dimensional address code cross-correlation value was given from the shift of discrepancy of location “1” of arbitrary two codes among codes with occuring of the collision of “1”. By using this method, some of the typical one-dimensional code cross-correlation value distribution was analyzed, the average cross-correlation value formula was given by using the probability analysis method, then on the basis of one-dimensional address code analysis, the algorithm of the symmetric two-dimensional code ф(N×L,w,1) cross-correlation value distribution was given.
