A Note on the Optimal Quadriphase Sequences Families
Xiaohu Tang, Udaya Parampalli · IEEE Transactions on Information Theory · 2007
In this note, by using a modification of the families B and C, we obtain a larger family of optimal quadriphase sequences, D over Z4. In contrast to the families B and C, the family D has the same length and the same maximal nontrival correlation value, but with double the size
