摘要

摘要: 为了减少零相关区序列设计中对相关参数的限制，基于任意一个周期大于4的最佳自相关序列，运用交织技术和递归运算，提出了一类新型的接近最优零相关区序列集的构造方法.通过递归运算，在保持ZCZ (zero correlation zone) 序列集包含的序列数目不变的条件下，可以将序列长度和零相关区宽度成倍扩展.构造的ZCZ序列集接近理论界，可应用于准同步CDMA (code division multiple access) 通信系统，消除共道干扰，提高通信质量.

Abstract: Abstract: To reduce the limit on the relevant parameters during constructing zero correlation zone (ZCZ) sequences, a novel construction method was proposed to design the near-optimal sequence set with ZCZ. Using the interleaving technique and recursive algorithm, a new ZCZ sequence set can be generated from an arbitrary perfect sequence with a period longer than 4. With the size (i.e. the number of sequences) of the new sequence set kept unchanged, the length and ZCZ width of the new sequence can be doubled by each recursive operation. The constructed near-optimal ZCZ sequence set can approach the mathematical bound, and can successfully provide quasi-synchronous CDMA communication without co-channel interference.
