Low complexity algorithm for PAPR reduction in GFDM system
Dianxin kexue, 2021 In order to reduce the peak-to-average power ratio (PAPR) and the implementation complexity of generalized frequency division multiplexing (GFDM) system, the TSLM algorithm based on T-transform and selective mapping (SLM) was proposed.The design idea of ...

A family of transformed copulas with singular component [PDF]
arXiv, 2017 In this paper, we present a family of bivariate copulas by transforming a given copula function with two increasing functions, named as transformed copula. One distinctive characteristic of the transformed copula is its singular component along the main diagonal. Conditions guaranteeing the transformed function to be a copula function are provided, and

Range Description for an Attenuated Conical Radon Transform with Fixed Central Axis and Opening Angle [PDF]
arXivThe conical Radon transform is an integral transform that maps a given function $f$ to its integral over a conical surface. In this study, we invesgate the conical Radon transform with a fixed central axis and opening angle, considering the attenuation of radiation within the transform.
