Design of Zero Correlation Zone Sequences via Interleaving Perfect Sequence
Wang Xian · Journal of Southwest Jiaotong University · 2012
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.
