An Efficient Application of Turbo Coding for OFDM In-Phase/Quadrature Index Modulation

IEEE Access, 2023
We present a method to efficiently apply turbo coding to OFDM in-phase/quadrature index modulation (OFDM-IQ-IM) for both cases of presence and absence of puncturing.

Entanglement-assisted quantum turbo codes [PDF]

, 2013
An unexpected breakdown in the existing theory of quantum serial turbo coding is that a quantum convolutional encoder cannot simultaneously be recursive and non-catastrophic.

Hydrodynamic Performance Assessment of Selected Hydrokinetic Turbine Blade Sections in River Oyun, North-Central Nigeria [PDF]

Journal of Renewable Energy and Environment
The hydrodynamic performance of lift-based hydrokinetic turbine rotors is typically dependent on the rotor blade sections, or the profile of the hydrofoil used.

Assessment of the Impact of Turbo Factor on Image Quality and Tissue Volumetrics in Brain Magnetic Resonance Imaging Using the Three-Dimensional T1-Weighted (3D T1W) Sequence

International Journal of Biomedical Imaging, 2023
Background. The 3D T1W turbo field echo sequence is a standard imaging method for acquiring high-contrast images of the brain. However, the contrast-to-noise ratio (CNR) can be affected by the turbo factor, which could affect the delineation and ...

Soft-Decision-Driven Channel Estimation for Pipelined Turbo Receivers [PDF]

, 1999
We consider channel estimation specific to turbo equalization for multiple-input multiple-output (MIMO) wireless communication. We develop a soft-decision-driven sequential algorithm geared to the pipelined turbo equalizer architecture operating on ...

Gas Turbine-Based Binary Working Fluid Gas Compression Energy Storage System

南方能源建设
[Objective] The efficiency of existing compressed air energy storage is insufficient, and site selection is restricted by gas storage conditions, which hinders large-scale deployment of compressed air energy storage.

The effect of volute surface roughness on the performance of automotive turbocharger turbines

Journal of the Global Power and Propulsion Society, 2017
The roughness level of the turbine housing’s internal surfaces can affect the total pressure loss, and hence the efficiency, of turbine stages for automotive turbochargers significantly.

An Energy Storage System with Binary Cycle Gas Compressionand Its Feasibility Analysis

南方能源建设
[Introduction] The compressed air energy storage system has a very large air storage volume and high pressure, and usually uses the underground salt cavern as the gas storehouse. Project development is constrained by scarce salt cavern resources.
