报告简介：Spectrally constrained sequences (SCSs) play an important role in modern communication and radar systems operating over non-contiguous spectrum. Despite numerous research attempts over the past years, very few works are known on the constructions of optimal SCSs with low cross-correlations. In this talk, we address such a major problem by introducing a unified framework to construct unimodular SCS families using circular Florentine rectangles (CFRs) and interleaving techniques. We also present a tighter correlation lower bound and show that it is achievable by our proposed SCS families including multiple SCS sets with zero correlation zone properties.
