Low-Complexity Distortionless Techniques for Peak Power Reduction in OFDM Communication Systems
Journal of Computer Networks and Communications, 2012 A high peak-to-average power ratio (PAPR) is one of the major drawbacks to using orthogonal frequency division multiplexing (OFDM) modulation. The three most effective distortionless techniques for PAPR reduction are partial transmit sequence (PTS ...

Advanced Engineering Materials, EarlyView.CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.

Global Complex Roots and Poles Finding Algorithm Based on Phase Analysis for Propagation and Radiation Problems [PDF]
IEEE Transactions on Antennas and Propagation, 2018 A flexible and effective algorithm for complex roots and poles finding is presented. A wide class of analytic functions can be analyzed, and any arbitrarily shaped search region can be considered. The method is very simple and intuitive. It is based on sampling a function at the nodes of a regular mesh, and on the analysis of the function phase.
