Secure Transmission for TDCS Using 4-WFRFT and Noise Insertion
工程科学与技术, 2016 :In order to guarantee the physical layer security of the transform domain communication system (TDCS)， a security-enhanced scheme based on 4-Weighted-type Fractional Fourier Transform (4-WFRFT) and artificial noise insertion was proposed. Firstly, the 4-

Coded Multi-dimensional Spreading System using Discrete Fourier Transform
, 2015 In this paper a novel coded multi-dimensional spreading technique using the Discrete Fourier Transform (DFT) is introduced. It exploits the DFT characteristic of spreading one symbol in one domain to all the symbols in the corresponding transform domain.

Finite Element Analysis for Li Batteries at the Mesoscale
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Finite element analysis (FEA), through multi‐physics coupling, has been widely employed to calculate mesoscale structures in LIBs that exhibit inherent randomness and disorder (Figure a). It has been extensively applied to the investigation of critical phenomena such as Li dendrite evolution, Li+ concentration gradients, SEI film growth, particle ...
