DOI: 10.1109/lcomm.2024.3513934
Abstract: In this letter, we propose a frequency-domain improved proportionate normalized least mean square based sparse direct adaptive equalization (FD-IPNLMS-SDAE) algorithm for underwater acoustic communication. Compared with the existing methods, the proposed algorithm is implemented in… read more here.

DOI: 10.1364/oe.550487
Abstract: We propose to track state of polarization (SOP) rotation by utilizing chirp pilots processed through fractional Fourier transform (FrFT). Superimposed on dual-polarization data signal, the chirp pilots with different FrFT rotation orders can converge to… read more here.
