Combined turbo equalization and turbo decoding [PDF]

open access: yesGLOBECOM 97. IEEE Global Telecommunications Conference. Conference Record, 1998
In this paper, the subject of turbo coding in the presence of intersymbol interference channel is investigated. An iterative decoder structure is presented, which combines the channel equalization and the turbo decoding. At each iteration extrinsic information from the channel detector is fed into the turbo decoders, and then their extrinsic ...

Effect of Mistuning and Blade Passing Frequencies on a Turbine’s Integral Mode Blade Vibration Detection Using a Pulsation Probe

open access: yesInternational Journal of Turbomachinery, Propulsion and Power, 2023
For engines operating using heavy fuel oil (HFO), the nozzle rings of turbocharger turbines are prone to severe degradation because of contamination with unburned fuel deposits. This contamination may lead to increased excitation of blade resonance.
