On Zero Correlation Window Complementary Access Code Design
具有零相关窗互补地址码的设计

A binary tree scheme to construct Zero Correlation Window (ZCW) complementary codes is presented. The gap between the code number of the construction method and that of the theoretic bound is at most one when the code is long enough. In order to obtain more usable codes, a set of codes can be constructed through the direct product of the complementary code and an extend matrix. The correlation property of the code in one set lies on the extend matrix, nevertheless the ZCW still exists between any two codes in any different code sets.
