| 摘 要： | 为了减少参数限制对零相关区序列集构造的影响,文中提出一种零相关区序列集扩展方法.该方法将初始序列成对地进行交织变换从而构造出序列长度和零相关区都加倍的新序列集.在初始序列集具有最优参数且集合容量为偶数时,新序列集能够保持参数的最优性.该方法同样适用于零相关区序列偶集的扩展,且能够迭代进行从而获得更多的序列集.数值仿真验证了该方法的有效性.

| Abstract: | To reduce the impact of the limit of parameters for the construction of zero correlation zone （ZCZ） sequence sets, an extension method is derived in this paper. The original sequences are interleaved in pairs to construct new sequence set with doubled sequence length and ZCZ. When the original sequence set obtains the optimal parameters and the volume is even, the new sequence set can keep the parameter optimality. This method is also applied to the extension of ZCZ sequence pair sets. It can be used iterative- ly to achieve more sequence sets. Numerical simulation proves the validity of this method. |
