    Abstract: In a method for error correcting a data signal that is transmitted via a channel and contains data blocks with associated error checking information, the data signal is first equalized, with calculated soft-bit information. In a subsequent step, the error checking information is evaluated with respect to the data block. If the evaluation of the error checking information shows that a single bit error is present in one message bit, the single bit error is corrected only when a condition that is dependent on the soft-bit information is satisfied.

    Abstract: A method for increasing bulkiness of reconstituted tobacco by adding tobacco stem particles includes (1) pulverizing a first portion of tobacco stems to obtain tobacco stem particles; (2) classifying the tobacco stem particles with mesh sieves and selecting the tobacco stem particles with a predetermined mesh size; (3) extracting a second portion of the tobacco stems with water and grinding to form a tobacco stem slurry that has a beating degree of 12-14° SR, and mixing the tobacco stem slurry with tobacco leaves in a weight ratio of 6:4 and grinding to obtaining a tobacco slurry that has a beating degree of 18-20° SR; (4) cutting plant fiber pulp boards and dispersing in water to form a plant fiber pulp; (5) preparing a filler solution that contains 10 wt % of a mineral filler; (6) mixing, rolling and drying to obtain the reconstituted tobacco.
