Performance of constant envelope OFDM system with nonlinear power amplifier by Qingbo WANG

“…Orthogonal frequency division multiplexing technology is widely used in wireless communication system due to its high spectral efficiency and good resistance ability to frequency selective fading.But it has high peak-to-average power ratio.Therefore,OFDM system needs large input power back-off to avoid signal distortion when using nonlinear power amplifier.In order to study the performance of the system under the condition of nonlinear power amplifier,the implementation of constant envelope OFDM was analyzed.Taking bit error rate as an index,the performance comparison between CE-OFDM system and OFDM system using traditional iterative limiting filter PAPR suppression technology were given under additive white Gaussian noise channel and multipath fading channel.…”

Progesterone induces meiosis through two obligate co-receptors with PLA2 activity by Nancy Nader, Lama Assaf, Lubna Zarif, Anna Halama, Sharan Yadav, Maya Dib, Nabeel Attarwala, Qiuying Chen, Karsten Suhre, Steven Gross, Khaled Machaca

“…This PLA2 activity bifurcates P4 signaling by inducing clathrin-dependent endocytosis of mPRβ, resulting in the production of lipid messengers that are G-protein coupled receptor agonists. Therefore, P4 drives meiosis by inducing an ABHD2 PLA2 activity that requires both mPRβ and ABHD2 as obligate co-receptors.…”
