Performance analysis of spatially modulated differential chaos shift keying modulation
IET Communications, 2017 A high‐data‐rate differential chaos shift keying (DCSK) scheme based on spatial modulation (SM), spatially modulated DCSK (SM‐DCSK), is proposed. By employing multiple transmit antennas and using transmit antenna index as information‐carrying unit, the proposed scheme offers a higher data rate compared with the conventional DCSK scheme.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.

Natural Killer Cells in Paediatric Soft Tissue Sarcomas: A Systematic Review
Pediatric Blood &Cancer, EarlyView.ABSTRACT Paediatric soft tissue sarcomas (pSTS) are a rare and heterogeneous group of malignant tumours arising in tissues of mesenchymal origin. The role of natural killer (NK) cells in pSTS remains poorly understood, with evidence fragmented across small preclinical studies and early‐phase clinical trials.

Differential spatial modulation scheme based on orthogonal space-time block coded
Tongxin xuebao, 2017 Focusing on the problem that differential spatial modulation (DSM) couldn’t obtain transmit diversity and has high decoding complexity,a new differential spatial modulation scheme based on the orthogonal space-time block code was proposed and the ...
