A method for decoding a predetermined code word is specified in which the code word comprises a number of positions having different values. In this method, encoding is performed, in particular, by way of a terminated convolutional code. Each position of the code word is correlated with a safety measure (soft output) for a most probable Boolean value by performing the correlation on the basis of a trellis representation. The decoding of the code word is determined by the correlation of the individual positions of the code word.

Soft decision decoding of a scheduled convolutional code

A method and arrangement for the design of a technical system measured data of a given system are described on the basis of an equivalent model. In a dimensional coefficient for the quality of the equivalent model is thereby determined in that the measured data of the system are compared to data defined by the equivalent model. The equivalent model is adapted on the basis of the dimensional coefficient in view of an optimally high quality. The dimensional coefficient is improved on the basis of additional measured data, and the adapted equivalent model is utilized for the design of the technical system.

Method and device for designing a technical system

A method and system for screening out empirically data collected from various steps of a technical process operating based on a first set of parameters, by utilizing a screening algorithm to reduce the size of the empirical data set, thus improving the modeling and revising of the technical process. The algorithm utilizes various classes associated with the empirical values and within each class performs an assessment with respect to preselected threshold values. The algorithm also performs an assessment with respect to another preselected threshold value, for the class as a whole.
