Abstract: To evaluate the branch metrics during the decoding of convolutional code signals, current branch metrics are in each case added to previously determined metric information items. The results of the addition which originate from in each case opposite branch metrics are compared with one another in the logic domain. The extreme-value metrics are then in each case selected from each comparison result and from all comparison results. From each selected extreme-value metric function, the metric function with the most extreme value, that is to say the metric function with the most extreme value of all comparison results, is subtracted and the metric information items stored in in each case one memory are updated with the result of the subtraction. The processing at the logic and arithmetic level of operations is distributed in such a manner that fast information processing is possible.

Inventor: ONDERKA BERND
IPC: B21B37/46
Filed: 1989-06-19
Abstract: When rolling sections in universal stands of continuously operating section rolling mill trains, it has been found that changes in the speed ratios between the horizontal rolls and the vertical rolls lead to undesired material flow changes. As a result of the horizontal roll speed, the deformation in the section parts, the resulting transverse flow and the external forces at the roll gap, a certain speed is produced in the vertical rolls in proportion to the horizontal roll speed. Any change of the edge conditions of the rolling process leads to a change of the speed ratios between horizontal and vertical rolls. In order to eliminate these disadvantages, it is proposed to control the speed of the vertical rolls of the universal stands to influence optimally the horizontal roll speed and the vertical roll speed via a control device and to obtain a minimal pull between stands via a further control.
