低相关区屏蔽序列偶集的构造

Construction of Low Correlation Zone Punctured Sequence Pairs Set

摘要:

将伪随机屏蔽序列偶应用于低相关区(LCZ)序列偶集的构造中,提出一种低相关区屏蔽序列偶集的构造方法.基于伪随机屏蔽序列偶,通过不同的移位序列和正交矩阵,采用交织方法生成具有一定长度、序列偶数目和低相关区长度的LCZ屏蔽序列偶集,对构造方法进行了理论证明和举例说明.该构造方法也可基于广义伪随机屏蔽二进序列偶构造LCZ屏蔽序列偶集.由于LCZ序列偶集存在的范围更加广阔,可为实际的工程应用提供更多的选择.

Abstract:

Pseudorandom punctured sequence pairs were applied to the construction of low correlation zone(LCZ)sequence pairs set; a new construction method for LCZ punctured sequence pairs set was presented.According to different shift sequences and orthogonal matrix,LCZ punctured sequence pairs set with a certain length,sequence pairs number,and low correlation zone could be generated through interleaved technique based on pseudorandom punctured sequence pairs.The construction method was theoretically proved and some examples were given.This method could also be used for constructing LCZ punctured sequence pairs set based on generalized pseudorandom punctured binary sequence pairs.There were more choices for engineering application because the LCZ sequence pairs exist in a larger scope.
