Comparative study of turbo equalization schemes using convolutional, convolutional turbo, and block-turbo codes [PDF]
IEEE Transactions on Wireless Communications, 2002 Turbo equalizers have been shown to be successful in mitigating the effects of inter-symbol interference introduced by partial response modems and by dispersive channels for code rates of R/spl les/ 1/2. We comparatively studied the performance of a range of binary phase-shift keying turbo equalizers employing block-turbo codes, namely Bose-Chaudhuri ...

Combined turbo equalization and turbo decoding [PDF]
IEEE Communications Letters, 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 ...

Turbo Equalization With Irregular Turbo Codes [PDF]
2007 4th International Symposium on Wireless Communication Systems, 2007 We analyze a turbo equalization system that combines maximum a posteriori probability (MAP) equalization with irregular turbo codes. Our goal is to approach the information capacity limit for severe inter-symbol interference (ISI) channels. To this end, we optimize the degree profile of irregular turbo codes by maximizing the minimum distance between ...

On the Convergence Speed of Turbo Demodulation With Turbo Decoding [PDF]
IEEE Transactions on Signal Processing, 2012 Iterative processing is widely adopted nowadays in modern wireless receivers for advanced channel codes like turbo and LDPC codes. Extension of this principle with an additional iterative feedback loop to the demapping function has proven to provide substantial error performance gain.

International 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.

Current vehicle emission standards will not mitigate climate change or improve air quality
Scientific Reports, 2023 The vehicle emissions testing programme was conducted by the UK Department of Transport in 2016 in response to emissions tampering exposed in the Volkswagen (VW) emissions scandal. The programme identified large emissions discrepancies between real-world
