The present paper introduces a new construction of a class of binary periodic sequence set having a zero-correlation zone sequence set. The cross-correlation function and the side-lobe of the auto-correlation function of the proposed sequence set is zero for the phase shifts within the zero-correlation zone.

Perfect Sequences of Odd Prime Length
IEEE Signal Processing Letters, 2018A sequence is said to be perfect if it has an ideal periodic autocorrelation function. In addition, the degree of a sequence is defined as the number of distinct nonzero elements within each period of the sequence. This study presents a systematic method for constructing perfect sequences (PSs) of odd prime periods, where the general constraint ...

Perfect sequences for belief networks representation
Proceedings 13th IEEE International Conference on Tools with Artificial Intelligence. ICTAI 2001, 2002In contrast to most other approaches used to represent multidimensional probability distributions, which are based on graphical Markov modelling (i.e. dependence structure of distributions is represented by graphs), the described method is rather procedural.

On Integer-Valued Almost-Perfect Sequences
IEEE Communications Letters, 2015In this letter, a new class of integer-valued sequences with almost-perfect periodic autocorrelation function is proposed. To construct these sequences, two groups of base sequences with two and four base sequences in each group are developed, and each base sequence is generated from a generalized Hadamard matrix.

Almost p-Ary Perfect Sequences
2010A sequence a = (a0, a1, a2, ..., an) is said to be an almost p-ary sequence of period n + 1 if a0 = 0 and ai = ξpbi for 1 ≤ i ≤ n, where ξp is a primitive p-th root of unity and bi ∈ {0, 1, ..., p - 1}. Such a sequence a is called perfect if all its out-of-phase autocorrelation coefficients are zero; and is called nearly perfect if its out-of-phase ...

Binary Alexis sequences with perfect correlation
IEEE Transactions on Communications, 2001Summary: Binary Alexis sequences are useful signals for fast startup equalization, channel estimation, synchronization, or ranging. The aperiodic autocorrelation functions of Alexis sequences vanish in a broad window region when correlated using additional binary preamble and postamble sequences.

In the paper, some new almost-perfect (AP), odd-perfect (OP) and perfect polyphase and almost-polyphase sequences derived from the Frank and Milewski sequences are presented. The considered almost-polyphase sequences are polyphase sequences with some zero elements.
