The recently proposed loosely synchronized (LS) spreading code can in principle realize an
intracell-interference-free quasi-synchronous code-division multiple-access (QS-CDMA) …

Motivated by applications in communications, we consider linear discrete-time systems over
the finite ring [Formula: see text]. We solve the open problem of deriving a theory of row …

We determine the exact values of the linear complexity of 2p-periodic quaternary sequences
over Z_4 (the residue class ring modulo 4) defined from the generalized cyclotomic classes …

Sequences with high linear complexity property are of importance in applications. In this
paper, based on the theory of generalized cyclotomy, new classes of quaternary generalized …

We define a family of quaternary sequences over the residue class ring modulo 4 of length
pq, a product of two distinct odd primes, using the generalized cyclotomic classes modulo pq …

In this correspondence, we present a new family of nonbinary sequences with three-level
nontrivial correlations and large linear complexity. The sequences may be considered as …

In this paper, for an odd prime p and an integer n≧3, a new family of p-ary sequences of
period p^n-12 with low correlation is constructed. The new family is constructed by shifts and …

Let p= ef+ 1 be an odd prime, where e≡ 0 (mod 4). A family of balanced quaternary
sequences is defined by using the classical cyclotomic classes of order e with respect to p in …

Recently, a class of quaternary sequences with period pq, where p and q are two distinct
odd primes introduced by Zhang et al. were proved to possess high linear complexity and 4 …

The linear complexity of quaternary sequences plays an important role in cryptology. In this
paper, the minimal polynomial of a class of quaternary sequences with low autocorrelation …
