We present a new construction of a family of perfect ternary sequences (PTSs) that is a generalization of one of the known families of PTSs. These PTSs of length N1N2 are derived from shift sequences of odd length N1 corresponding to m-sequences over GF(p) and PTSs of odd length N2. Ipatov PTSs are a special case where N2 = 1. For N2 ≥ 3, we find conditions under which the obtained PTSs are new. We also consider implementation issues of these sequences. [ABSTRACT FROM AUTHOR]

In this letter, a new interleaved structure is improved and its interesting Local Coordinated Shifting (LCS) Property which is helpful in constructing longer sequences is emphasized. Then, making use of the interleaved structure, several methods for constructing perfect ternary sequences and three-level autocorrelation (0, 1) binary sequences are proposed. The LCS property and the demonstrational construction methods imply that this new interleaved structure is an interesting approach for constructing new sequences. [ABSTRACT FROM AUTHOR]
