Signal processing and neural computation have separately and significantly influenced many disciplines, but the cross-fertilization of the two fields has begun only recently. Research now shows that each has much to teach the other, as we see highly sophisticated kinds of signal processing and elaborate hierachical levels of neural computation ...

Turbo-Expander Applications in Natural Gas Processing
Journal of Petroleum Technology, 1976Turbo-expander processing is the better method for efficiency of liquids recovery in this comparison of choke and expander processing of a typical natural gas stream. The advantages of low-temperature, low-pressure separation of gas liquids are presented, along with a definition of situations in which only a combination of low temperature and low ...

Turbo Decoder with Parallel Processing
2013The operating frequency \(\mathcal{F}\) is the decisive factor in throughput calculation of conventional turbo decoders. Although the modification to circuits can improve this factor, there is a limit to the critical path delay, and it is difficult to supply a stable clock signal with high frequency.

Turbo-coded blind per-survivor processing multiuser detection CDMA [PDF]
11th IEEE International Symposium on Personal Indoor and Mobile Radio Communications. PIMRC 2000. Proceedings (Cat. No.00TH8525), 2002 Joint data and blind channel estimation based on the principle of per-survivor processing (PSP) is invoked and characterised in the proposed turbo-coded multiuser detection assisted code division multiple access (CDMA) system. The turbo-coded blind PSP receiver invoked the likelihood function in its metric calculations over the typical urban (TU) time ...

Multichannel processing of DVB/RCS turbo codes
CCECE 2003 - Canadian Conference on Electrical and Computer Engineering. Toward a Caring and Humane Technology (Cat. No.03CH37436), 2004Turbo decoder is one of the iterative decoders that its performance is very sensitive to the number of iterations it performs. In a multichannel turbo decoding system, each input frame requires different number of iterations to be decoded correctly. An example of these kinds of systems is the base station of mobile communication system, in which turbo ...

New schedules for information processing in turbo decoding
Proceedings. 1998 IEEE International Symposium on Information Theory (Cat. No.98CH36252), 2002The framework of Bayesian networks has been used to introduce new ways for decoding parallel concatenated convolutional (turbo) codes. Simulation results show that a noisy received block which does not converge using traditional turbo decoding can converge to the correct value with one or more of the methods introduced here.

Sliding-Window Processing of Turbo Equalization for Partial Response Channels
2019 26th International Conference on Telecommunications (ICT), 2019Spatially coupled low-density parity-check (SC-LDPC) codes are the attractive candidates for the application requiring a practical constraint on the latency and complexity. In previous works, the turbo equalization consisting the SC-LDPC window decoder and Bahl-Cocke-Jelinek-Raviv (BCJR) detector is used to tackle the inter-symbol interferences (ISIs ...

Block processing technique for low power turbo decoder design
Vehicular Technology Conference. IEEE 55th Vehicular Technology Conference. VTC Spring 2002 (Cat. No.02CH37367), 2003We apply a block processing technique to the MAP algorithm used in turbo decoding. This new technique leads to a power-efficient way to access memory and to a reduced memory size. We introduce the "very long data word" (VLDW) memory architecture, which leads to a reduction in power consumption for memory access operations.

Demands for turbo-molecular pumps in the aluminium etching process
Vacuum, 1990Abstract Turbo-molecular pumps used in etching processes have to fulfil special demands concerning corrosion stability. The rotor and stator are usually manufactured out of aluminium alloys. Chlorine containing etching gases such as Cl 2 , BCl 3 or CCl 4 strongly attack the rotor and stator.
