Abstract :
In this paper, we propose a novel zero-correlation zone (ZCZ) code, called m-ZCZ code. Both auto-correlation function (ACF) side lobes and cross-correlation function (CCF) of the code are zero within ZCZ, whose length can be adjusted in a very.´flexible manner. The m-ZCZ code can be generated using a simple method. If compared with conventional binary ZCZ codes, the m-ZCZ code can support more users while still retaining the same interference-resist capability.
