Outline of the Talk:

Optimal Aperiodic Peak Sidelobe Sequences and Polyphase Sequences with 2-level PACF

Sequences of various kinds have applications in radar, wireless communications, and many other diverse areas. As spectrum congestion increases, there is more reliance on sequences to provide multi-user communications and minimum ambiguity and low probability of intercept radar signals. Wi-Fi, Wi-max are commonplace examples. This talk presents current research into sequence design in scientific group at Mari State University. The sequence constructions and their applications will be described.

The talk shall give a short review of known results of sequences design for optimal binary sequences with ideal periodic autocorrelation function, perfect polyphase binary sequences, optimal binary sequences with minimum peak sidelobe level, and generalized (polyphase) Barker codes. Then, new algorithm for an exhaustive search of minimum peak sidelobe level binary sequences is demonstrated. The results of an exhaustive search of optimal binary sequences with minimum peak sidelobe level in the range of lengths N=[2,85] are shown. New analytical and numerical algorithms for design of polyphase Barker sequences are described, together with new polyphase Barker sequences. Finally, algebraic theory of design of polyphase sequences with two-level periodic autocorrelation function shall be discussed. Some new polyphase sequences with perfect periodic autocorrelation function are demonstrated.
