Low Autocorrelation Binary Sequences: Best-Known Peak Sidelobe Level Values

open access: yesIEEE 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.

A Scalable Arrangement Method for Aperiodic Array Antennas to Reduce Peak Sidelobe Level

open access: yesIEEE 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]

open access: yes2008 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 Based Waveform Optimization for OFDM Joint Radar-Communications [PDF]

open access: yes2020 17th European Radar Conference (EuRAD), 2021
We propose a novel joint radar communication waveform design method based on OFDM spectrum allocation to trade off radar and communication performance. The proposed approach combines the water filling optimization to maximize the communication rate for slow fading channels with windowing to reduce pulse compression peak sidelobe level (PSL) for the ...
