New Optimal Quadriphase Zero Correlation Zone Sequence Sets With Mismatched Filtering
Zhengchun Zhou, Xiaohu Tang, Daiyuan Peng · IEEE Signal Processing Letters · 2009
In this letter, based on a pair of mismatched binary sequences with perfect cross-correlation function (PCCF), a new method for constructing zero correlation zone (ZCZ) sequences sets with mismatched filtering is presented. The resultant optimal sets of quadriphase ZCZ sequence have flexible parameters and high efficiency. Compared with the one proposed by Trinh, our method gives cyclically distinct transmitted sequences and corresponding mismatched sequences at the receiver.
