Spectral Comb Shaping by Polar Codes
A scheme to select information indices in polar codes is proposed to form signals with spectral comb shapes under BPSK modulation, whereby the signal could be separated from periodic interference in spectrum. By selecting proper indices to load information bits in polar coding, a spectral comb shape signal is formed, which has periodic zeros and notch bands uniformly distributed in its frequency spectrum. Furthermore, to mitigate the negative impact of proposed polar code on the AWGN performanc…

Measurements of the Diffuse Interstellar Bands at 5780, 5797, and 6614 Å in the Hot Stellar Spectra of the LAMOST LRS DR10
Diffuse Interstellar Bands (DIBs) are crucial tracers of the interstellar medium (ISM), yet their carriers remain poorly understood. While large-scale surveys have advanced DIB studies in cool stellar spectra, measurements in hot stellar spectra are still limited. Using 287 277 high signal-to-noise (S/N $>$ 50) hot stellar spectra from the tenth data release of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope low-resolution spectroscopic survey (LAMOST LRS DR10), we systematically …
