Highly Selective and Efficient Transport of Au(III), Pt(IV), and Pd(II) from Hydrochloric Acid Across Polymer Inclusion Membranes Containing Ionic Liquid as Ion Carrier [PDF]

open access: yesMembranes
Ionic liquid (IL) N-methyl-N′-1-(4-t-butylphenylphosphinyl)butylimidazolium bis(trifluoromethylsulphonyl) imide was used for the first time as an ion carrier in membrane systems to selectively transport Au(III), Pt(IV), and Pd(II) ions.

Multi-Format Carrier Phase Recovery Using a Programmable Circuit [PDF]

open access: yesOSA Advanced Photonics Congress 2021, 2021
We introduce an application-specific circuit that can be programmed to ef- ficiently perform blind carrier phase recovery for different modulation formats. A circuit implementation that supports QPSK/16/32/64QAM is evaluated.

Nonlinear analysis of GMSK carrier phase recovery loop [PDF]

open access: yes2016 International Symposium on Signal, Image, Video and Communications (ISIVC), 2016
Deep space communication systems operate in the presence of high atmospheric attenuation and the capacity of the on-board energy generator is limited which produces a very low signal to noise ratio (SNR) at the reception. In order to satisfy the required transmission quality of deep space mission in terms of power and spectral efficiency, a coherent ...

An Approach to Wideband and High Accuracy Microwave Photonic Signal Carrier Recovery Based on Carrier Period Measurement

open access: yesIEEE Photonics Journal, 2019
We propose and experimentally demonstrate an approach to carrier frequency and phase recovery of a microwave photonic signal based on carrier period measurement (CPM). In the approach, a coarse carrier frequency offset (CFO) estimation is first performed,
