A system is presented that provides real-time performance for iterative multi-user detectors, such as Turbo MUDs, which are used to separate simultaneous transmissions on the same frequency, by permitting the MUD to use a less computationally intense, fast-processing algorithm and to correct for errors caused by the fast processing. In order to reduce the errors, a voting system is coupled to the output of the multi-user detector within the iterative system. The voting system provides confidence values on a bit-by-bit basis for the estimates made by the multi-user detector, with the confidence values then being utilized as soft inputs to a bank of conventional single-user decoders.

A single stage low pressure turbine vane includes an airfoil having a profile substantially in accordance with at least an intermediate portion of the Cartesian coordinate values of X, Y and Z set forth in Table 2. The X and Y values are distances, which when smoothly connected by an appropriate continuing curve, define airfoil profile sections at each distance Z. The profile sections at each distance Z are joined smoothly to one another to form a complete airfoil shape.

The present invention relates generally to the use of compressors, with an optional noise extractor, to improve audio sensing performance of one or more microphones. The audio sensing performance of a single element microphone array with dynamic range compression can be improved by the use of a noise extractor, to modify the operation of the compressor, typically to avoid noise floor amplification. Dynamic range compression can be applied to the output of two or more element microphone array processing with the optional use of a noise extractor. Dynamic range compression can precede the microphone array processing with the optional use of a noise extractor. Syllabic dynamic range compression may be used in one or more element microphone arrays, with the optional use of a noise extractor, which increases speech recognition accuracy.

The data processor executes an instruction having a direction for write to a reference register of other instruction flow and an instruction having a direction for reference register invalidation. The data processor is arranged as a data processor having typical functions as an integrated whole of processors (CPU1 and CPU2) which execute simple instruction flows. When executing the instruction having a direction for write to a reference register of other instruction flow, the processor confirms whether a write register is invalid. The processor waits for the register to be made invalid, if the register is not invalid, and performs write if the register is invalid. After having executed the instruction having a direction for reference register invalidation, the processor invalidates the register to which a reference has been made. When the reference register is invalid, execution of the referring instruction is suspended until it is made valid.
