Abstract: A method for channel coding in a digital telecommunication system, the method having error protection coding and interleaving, a coherent puncturing and interleaving rule determined in a common calculation step being applied for puncturing of a predetermined error protection coding master code and the interleaving, the rule having been determined under the criterion of optimizing the distance properties after interleaving.

Abstract: A method is provided for channel coding a parameter whose values are correlated with one another to different extents and according to which code words with better distance properties are at least partially associated with the more strongly correlated values of the parameters, and code words with weaker distance properties are at least partially associated with the more weakly correlated values of the parameter.

Abstract: A method and device for providing error protection for a data bit stream in a digital telecommunications transmissions transmission system in order to reduce the bit error rate, characterized in that wherein, before channel coding, a multiplicity number of previously known dummy bits are inserted in a non-terminating fashion at predetermined bit positions in a primary data bit stream near to on both sides of information-carrying bits, in particular on both sides thereof.

Abstract: A method is provided for decoding and/or detecting data containing user information which is received by a communication network in order to provide a way to suppress error concealment and to provide improved error correction. The present invention is characterized in that a receiver of a communication terminal and a CTM-receiver exchange at least additional information relating to the reliability of the correct reception of the data thus received and that error processing of the data thus received is adjusted in a receiver.

Abstract: The present invention relates to an effective option for recognizing error concealment, provided by a method and a device for evaluating data containing useful information that has been received via a communications network. The present invention is characterized in that the use of error concealment is detected after receipt through a statistical analysis of the useful information.

Abstract: A method for manufacturing ROM memory devices. The method includes forming a trench isolation structure within a cell region of a semiconductor substrate. The cell region is an array region for ROM memory devices. The method includes forming a gate structure within the cell region and forming a sidewall spacer on the gate structure, which is configured to overlap a portion of the trench isolation structure within the cell region to separate a buried bit line region of the cell region from an adjacent cell region. The method applies a refractory metal layer overlying the gate structure including sidewall spacers and exposed portion of the trench isolation structure. A step of alloying the refractory metal layer to the gate structure and exposed portions of source/drain regions to form silicided regions overlying the gate structure and source/drain regions is included. The refractory metal layer is selectively removed from sidewall spacers and exposed portion of the trench isolation structure.

Abstract: In a method, and a signal processing arrangement, for coding information, the information symbol sequences are first sorted in accordance with the probability of occurrence of the symbols in the sequences, and are then mapped to the natural binary code. This allows redundant information contained in the symbol sequences to be used for decoding the bit positions.

Abstract: A method is provided for converting input bits into modulation symbols. The modulation symbols include bit positions which are differentiated at least partially in terms of their channel error sensitivity. Convolutionally coded input bits are generated from the input bits using generator polynomials with a prioritization value being allocated to each of the convolutionally coded input bits. The reproduction of the convolutionally coded input bits on the bit positions of the modulation symbols is carried out, taking into account both the channel error sensitivity of the bit positions of the modulation symbols and the prioritization value of the convolutionally coded input bit.
