Nonbinary sequences with perfect and nearly perfect autocorrelations
2010 IEEE International Symposium on Information Theory, 2010The design of pseudorandom sequences with optimal correlation properties forms a crucial part of communications and radar engineering. Perfect autocorrelation sequences are however exceedingly rare. We discuss a technique that yields examples of such designs over enlarged PSK (PSK+) alphabets.

Unimodular Perfect and Nearly Perfect Sequences: a Variation of Björck’s Scheme
IEEE Transactions on Information Theory, 2023Constant Amplitude (CA), Zero Auto Correlation (ZAC) sequences (or CAZAC sequences, aka perfect sequences) have numerous applications. We generalize the CAZAC notion to what we term as CASAC by permitting small autocorrelations (SAC). We extend Björck’s classification result of two-valued CAZAC sequences by providing a complete classification of all ...

On non-existence of perfect and nearly perfect sequences
International Journal of Information and Coding Theory, 2009We study the complex p-ary perfect and nearly perfect sequences where p is an odd prime and show that the existence of such sequences is equivalent to the existence of certain kinds of difference sets. Using results from difference sets, there are no p-ary perfect sequences of length p3 for s ≥ 3, 2p3 for s≥1, and pq for prime q > p. Also, there are no

The synthesis of perfect sequences
1995Perfect sequences find application in many areas including synchronisation techniques, channel estimation, fast start-up equalization, pulse compression radars and CDMA systems. This paper will first discuss the necessary and sufficient condition for, and some useful properties of, perfect sequences. Then, a comprehensive description of various perfect

IEEE Wireless Communications Letters, 2012
This letter investigates the construction methods of perfect 8-QAM+ sequences, which relate to one of three open problems proposed by Boztas and Parampalli in 2010, and two constructions that transform the known perfect ternary sequences (PTSs) into the required sequences are presented.
