Frequency-Selective PAPR Reduction for OFDM [PDF]
, 2019 We study the peak-to-average power ratio (PAPR) problem in orthogonal frequency-division multiplexing (OFDM) systems. In conventional clipping and filtering based PAPR reduction techniques, clipping noise is allowed to spread over the whole active ...

iMeta, Volume 5, Issue 2, April 2026.Spatial multi‐omics defines a DLL4–NOTCH3–driven capillary–mCAF axis orchestrating fibrotic remodeling and immune exclusion in hepatocellular carcinoma tumor cores, conferring immune checkpoint blockade resistance. Targeting stromal NOTCH3 disrupts this pro‐fibrotic niche, enhances T cell infiltration, and synergizes with anti‐PD‐1 therapy ...

Low Complexity Golden Code Analytical and Deep Learning-Based Sphere-Decoders for High-Density M-QAM
IEEE Access, 2022 In this paper, we develop low complexity Golden code sphere-decoding (SD) algorithms for high-density M-ary quadrature amplitude modulation (M-QAM). We define the high-density M-QAM as having modulation orders ( $M$ ) of at least 64, i.e.
