Chromatic Dispersion Equalization FIR Digital Filter for Coherent Receiver

open access: yesPhotonics, 2021
Chromatic dispersion equalization (CDE) in coherent optical communication systems is extremely critical for subsequent digital signal processing (such as frequency offset estimation and carrier phase recovery).

Digital frontend design for three-bands aliasing RF signals

open access: yesDianzi Jishu Yingyong, 2019
In order to solve the problem of three-band bandpass signal aliasing, a delay-adjustable third-order bandpass sampling structure is proposed. By designing a digital anti-aliasing filter, the alias-free reception of three-band bandpass signals can be ...

Thermal Modelling and Simulation of Parabolic Trough Receiver Tubes [PDF]

open access: yes, 2010
Receiver tubes (or heat collecting elements — HCE) are a key component of parabolic trough solar thermal power plants. They are mounted in the focal line of the collectors, absorb the concentrated solar irradiance and transfer the absorbed energy to the ...
