Construction of Low Correlation Zone Punctured Sequence Pairs Set

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.

Key words:low correlation zone; sequence pairs set; interleaved technique; orthogonal matrix; pseudorandom punctured sequence pairs
