Tone reservation technique combined with active constellation extension for PAPR reduction of OFDM signal by Fang LIU, Yong WANG

“…To overcome the drawbacks of existing tone reservation(TR) techniques,an efficient TR algorithm combined with active constellation extension (ACE-TR) was proposed for reducing the peak-to-average power ratio (PAPR) of or-thogonal frequency division multiplexing (OFDM) signal.By means of a specially designed iterative procedure and a joint optimization approach for PAPR and bit-error-rate (BER) performances,ACE-TR was able to obtain both an im-proved BER and minimized out-of-band interference while reducing the PAPR effectively.A comprehensive theoretical analysis was presented,and some important results including the bounds of achievable PAPR gain,BER bound,and maximum iteration number were derived.Specifically,by adaptively adjusting the iterative parameters in the optimization approach,more trade-off flexibility between PAPR reduction and BER performance can be offered to satisfy various de-sign requirements.Simulations demonstrate that ACE-TR can dramatically decrease the number of required it ions to reach the desired PAPR with low computation complexity.In addition,the transmitted OFDM symbols using the pro-posed ACE-TR have less in-band distortion and lower out-of-band spectral regrowth than traditional TR algorithms.…”

Spring-Interseeded Winter Rye Seeding Rates Influence Weed Control and Organic Soybean Yield by Kelly A. Nelson, Reid J. Smeda, Randall L. Smoot

“…Yields and gross margins for wide-row soybean were 8 to 55% greater than narrow-row (19-cm) soybean seeded at 494,000 or 742,000 seeds ha−1 which was probably due to flexibility for implementing cultivation. As interseeded rye rates increased from 67 to 200 kg ha−1, yields and gross margins for narrow-rows decreased. …”

Security communication and energy efficiency optimization strategy in UAV-aided edge computing by Xueyong YU, Lixiang QIU, Jianing SONG, Hongbo ZHU

“…The flexible mobility of the unmanned aerial vehicle (UAV) has attracted widespread attention in the mobile edge computing (MEC) system.However, the existence of eavesdroppers in the air makes it a huge challenge for its secure transmission.In order to solve the contradiction between high safe communication rate and low energy consumption, the concept of security communication energy efficiency was introduced, that was, the ratio between UAV safe communication transmission rate and UAV energy consumption.Firstly, to subject the task delay constraint, limited UAV CPU frequency and task offloading rate constraint, an offloading strategy was proposed to maximize the energy efficiency of secure communication by jointly optimizing the legal UAV hover location, CPU frequency allocation and distinguishing the complexity of computing tasks, while improving the security communication in the UAV-MEC scenario from the perspective of physical layer security.Secondly, to address the non-convex optimization problem, it was decomposed into three sub-problems that were solved with block coordinate descent and the successive convex approximation (SCA) methods respectively.The simulation results show that, with different task complexity, the proposed strategy can balance the relationship between the overall secure communication performance and energy consumption, while meeting the offloading requirements of ground terminals.And then it improves secrecy energy efficiency.…”

Lightweight Design Strategy and Performance Optimization of Spaceborne Core Network by Xi CHEN, Yiqun Zhao, Minghan ZHANG, Shan LU, Shihao WANG, Chengchen ZHANG, Xiaofan XU, Ping DU

“…With the growth of global communication demand, the spaceborne core network can not only reduce frequent signaling interactions between satellites and the ground, but also break through the constraints of geographical regions, providing strong support for the integrated network architecture of heaven and earth and global communication operations.However, due to the resource limitations of satellites and the dynamic and time-varying topology of satellite internet on a large scale, the deployment of traditional core network elements in spaceborne environments has encountered significant challenges.This article is dedicated to studying the challenges of lightweight, flexible deployment, and low latency in onboard core networks, aiming to explore new design strategies for onboard lightweight core networks and provide a solid theoretical foundation for global communication operations.Multiple lightweight strategies, including minimum network element set deployment, single network element function tailoring, interface protocol lightweight, network element fusion and reconstruction, platform architecture lightweight, and transmission protocol reconstruction were firstly studied.Then, detailed simulation experiments were conducted on the selected strategies, and the experimental results confirmed that the lightweight processing of the spaceborne core network has superior performance in resource allocation and signaling process.…”

MULTIAXIAL MANNED CENTRIFUGE INTENSITY VERIFICATION CALCULATION METHOD BASED ON MULTIBODY DYNAMICS by YUE CongZhen, NIU HongPan, WANG PengFei, FAN ZhiGeng, YIN JiaoMei

“…The traditional quasi-static static analysis method can only directly analyze the structural strength problem of no more than two-axis nested rotation, but the multi-axis manned centrifuge has three or more than three-axis nested rotation. The flexible multi-body dynamics method can be used to analyze and determine the strength of the multi-axis rotating structure of the motion path, but the calculation time is long and the resource consumption is large, so it is difficult to fully assess the intensity of the structure. …”
