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

Influence of Vane Structure on Flow Field in Turbo-air Classifier
Turbo-air classifiers have low classifying precision and efficiency, which are mainly resulted from its internal structure. In this study, based on the air flow trajectory equation, three structural types of guide vanes are designed including straight ...

Quantum Serial Turbo Codes [PDF]
We present a theory of quantum serial turbo-codes, describe their iterative decoding algorithm, and study their performances numerically on a depolarization channel. Our construction offers several advantages over quantum LDPC codes. First, the Tanner graph used for decoding is free of 4-cycles that deteriorate the performances of iterative decoding ...

Numerical Investigation: Effect of Stator Vanes on Turbocharger Turbine Performance
With reduced turbo lag and better transient response, the introduction of VTG stator guide vanes improved turbocharger performance at all the engine operating conditions. The VTG system accelerates and maneuvers exhaust gas flow to the turbine. Favorable

Comparative study of turbo equalization schemes using convolutional, convolutional turbo, and block-turbo codes [PDF]
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 ...

On Maximum Contention-Free Interleavers and Permutation Polynomials over Integer Rings [PDF]
An interleaver is a critical component for the channel coding performance of turbo codes. Algebraic constructions are of particular interest because they admit analytical designs and simple, practical hardware implementation. Contention-free interleavers
