Abstract

In this paper, multiple Z-complementary code sets (ZCCSs) with low inter-set cross-correlation based on circular Florentine arrays are proposed. The zero correlation zone (ZCZ) length <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$Z$</tex> is flexible and the parameters are optimal. The resultant multiple ZCCSs can provide advantages in application to multi-carrier code-division multiple-access (MC-CDMA) scheme. As a byproduct, asymptotically optimal low correlation zone comple-mentary sequence set (LCZ-CSS) can be derived by combining these ZCCSs.
