Low Autocorrelation Binary Sequences: Best-Known Peak Sidelobe Level Values
IEEE Access, 2021 Binary sequences are widely used in many practical fields, such as radar applications, telecommunications and cryptography. Finding low autocorrelation binary sequences with good peak side-lobe level (PSL) values is a difficult optimization problem.

Sequence Design to Minimize the Weighted Integrated and Peak Sidelobe Levels [PDF]
IEEE Transactions on Signal Processing, 2016 Sequences with low aperiodic autocorrelation sidelobes are well known to have extensive applications in active sensing and communication systems. In this paper, we consider the problem of minimizing the weighted integrated sidelobe level (WISL), which can be used to design sequences with impulse-like autocorrelation and zero (or low) correlation zone ...

A Scalable Arrangement Method for Aperiodic Array Antennas to Reduce Peak Sidelobe Level
IEEE Access, 2023 Peak sidelobe level reduction (PSLR) is crucial in the application of large-scale array antenna, which directly determines the radiation performance of array antenna. We study the PSLR of subarray level aperiodic arrays and propose three array structures:

Typical peak sidelobe level of binary sequences [PDF]
2008 IEEE International Symposium on Information Theory, 2008 For a binary sequence in given equation, the peak sidelobe level (PSL) is defined as by a certain equation. It is shown that the distribution of M(Sn) is strongly concentrated, and asymptotically almost surely, as per a derived equation. Explicit bounds for the number of sequences outside this range are provided. This improves on the best earlier known

Peak Sidelobe Level Reduction With a Hybrid Approach Based on GAs and Difference Sets [PDF]
IEEE Transactions on Antennas and Propagation, 2004 This paper presents an approach for the optimization of the beam pattern produced by massively thinned arrays. The method, which combines the most attractive features of a genetic algorithm and those of a combinatorial technique (namely, the difference sets method), is aimed at synthesizing massively thinned antenna arrays in order to suitably reduce ...

Two-phase optimization of binary sequences with low peak sidelobe level value
Expert Systems With ApplicationsThe search for binary sequences with low peak sidelobe level value represents a formidable computational problem. To locate better sequences for this problem, we designed a stochastic algorithm that uses two fitness functions. In these fitness functions, the value of the autocorrelation function has a different impact on the final fitness value.
