Efficient Selective Mapping PAPR Reduction Technique
Procedia Computer Science, 2015 AbstractOFDM is a form of multicarrier modulation technique with high spectral efficiency and immunity to interference. One major drawback of OFDM systems is the high peak to average power ratio (PAPR) which leads to power inefficiency and signal distortion with practical power amplifiers used at the transmitter. Selective Mapping (SLM) is a distortion

Exoproteomic Evidence for BcTSPO‐Mediated Regulation of Virulence Factors in Bacillus cereus
PROTEOMICS, Volume 25, Issue 7, April 2025.ABSTRACT Bacillus cereus translocator protein (BcTSPO) is a transmembrane protein that plays a regulatory role in various Bacillus cereus phenotypes, potentially including its virulence. Given that the exoproteome is a major determinant of B.

Current Protocols, Volume 5, Issue 3, March 2025.Abstract High concentrations of aerosols can be generated within the sort collection area of cell sorters during instrument failures that cause the stream to deviate, such as a partial nozzle obstruction. Complete containment of these aerosol particles becomes essential for operator safety when working with potentially infectious or hazardous samples ...

Clinical and Translational Medicine, Volume 15, Issue 2, February 2025.SHP2 plays a pivotal role as a signal transducer in the MAPK/ERK signaling pathway. SHP2 controls the cell cycle via the GSK3β/cyclin D1/Rb pathway in oncogenic KIT‐driven GIST. Inhibition of SHP2 synergizes with adjuvant therapy drugs in inhibiting KIT‐driven GIST with primary and secondary mutations both in vitro and in vivo. Abstract Background Most

A new PAPR reduction in OFDM systems using PTS combined with APPR for TWTA nonlinear HPA [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2008 In this paper, we propose a new Peak-to-Average Power Ratio (PAPR) reduction technique using a partial transmit sequence (PTS) combined with adaptive peak power reduction (APPR) methods.

A New Approach to Iterative Clipping and Filtering PAPR Reduction Scheme for OFDM Systems
IEEE Access, 2018 While achieving reduced/good peak-to-average power (PAPR) in orthogonal frequency division multiplexing (OFDM) systems is attractive, this must not be performed at the expense of the transmitted signal with over-reduced signal power, as it leads to ...
