New Construction of Complementary Sequence (or Array) Sets and Complete Complementary Codes (II)

Abstract

Previously, we have presented a framework to use the para-unitary (PU) matrix-based approach for constructing new complementary sequence set (CSS), complete complementary code (CCC), complementary sequence array (CSA), and complete complementary array (CCA). In this paper, we introduce a new class of delay matrices for the PU construction. In this way, generalized Boolean functions (GBF) derived from PU matrix can be represented by an array of size $2\times 2 \times \cdots \times 2$. In addition, we introduce a new method to construct PU matrices using block matrices. With these two new ingredients, our new framework can construct an extremely large number of new CSA, CCA, CSS and CCC, and their respective GBFs can be also determined recursively. Furthermore, we can show that the known constructions of CSSs, proposed by Paterson and Schmidt respectively, the known CCCs based on Reed-muller codes are all special cases of this new framework. In addition, we are able to explain the bound of PMEPR of the sequences in the part of the open question, proposed in 2000 by Paterson.
