Research on the Real-Time Phase Jump Process Method for Plasma Electron Density Measurement in HL-2A Tokamak

In the real-time plasma electron density measurement using far infrared (FIR) laser interferometry, the plasma electron density can be calculated by measuring the real time phase difference between the reference signal and the probe signal. A novel Real-time Phase Jump Process (RPJP) method is applied to the HL-2A tokamak. With this method, the phase difference […]

A Deterministic Localization Network for TDOA Measurement

In the industrial environment,the influence of the complex wireless communication on the localization network leads to poor real-time reliability and low accuracy of localization.This paper proposes the deterministic localization network model for TDOA(time difference-of-arrival) measurement in the case of asynchronous anchor nodes called ASync-DetNET.After that,we propose the sensing model and localization model,which can adapt to […]

VIDEO ENCRYPTION ALGORITHM COMBINING WAVELET TRANSFORM WITH CHAOS KEYING

In order to solve the problem that video encryption is difficult to balance the security and real-time requirements, we proposed a video encryption algorithm combining wavelet transform with chaos keying. We selected three-dimensional CNN system, three-dimensional Rosler system and three-dimensional Chen system as the key source. The initial value of the chaotic system, the selection […]
