在码集中任意取两个不同码字,从其码字之间的"1"的位置之差的移位下必发生"1"的碰撞出发,给出了一维地址码互相关值分布的算法,并用此方法分析了几种典型一维码的相关值分布,在此基础上验证了关于用概率分析法给出的求平均互相关值的式子,在一维地址码分析的基础上给出了对称二维码φ(N×Lw,1)的互相关值分布的算法.

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 codeφ(N×L, w, 1) cross-correlation value distribution was given.
