    摘要： Die vorliegende Erfindung ist auf ein Verfahren zur Verbesserung der Vorwärtsfehlerkorrektur bei serieller Kodierung bei einer Datenübertragung im Fahrzeug gerichtet und schafft gegenüber dem Stand der Technik unter anderem den Vorteil, dass trotz einer Reduzierung des Ressourcenbedarfs das physikalische Verhalten auf einem Übertragungskanal stets deterministisch kontrollierbar ist. Das vorgeschlagene Verfahren reduziert die Gatteranzahl bei den Vorwärtsfehlerkorrekturkodierern, dadurch, dass das vorgeschaltete Berechnen der Vorwärtsfehlerkorrektur auf einzelnen Teilwörtern das exponentielle Wachstum der Anzahl der benötigten Gatter gegenüber dem Stand der Technik minimiert wird. Es sind gemäß dem vorgeschlagenen Verfahren die Bitfehler minimal und ein Übertragungsfehler kann effizient, d.h. mit minimalem technischem Aufwand, korrigiert werden. Darüber hinaus sind die verwendeten Kodierer bezüglich ihrer Anzahl der Gatter minimal ausgestaltet und es ist dem vorgeschlagenen Verfahren eine Verschachtelung implizit, die darauf abstellt, dass sogenannte Burst Fehler besonders vorteilhaft korrigiert werden können. Diese implizite Verschachtelung ermöglicht es, dass die benötigten herkömmlichen Pufferspeicher einer expliziten Verschachtelung entfallen können. Darüber hinaus wird erfindungsgemäß sichergestellt, dass Nutzdaten mitsamt korrigierender Metadaten vorteilhaft bezüglich der Übertragung kodiert werden können. Erfindungsgemäß kann sichergestellt werden, dass nicht nur die Nutzdaten linienkodiert bzw. leitungskodiert werden, sondern eben auch die Korrekturdaten. Die vorliegende Erfindung ist ebenfalls auf eine analog ausgestaltete Systemanordnung zur Durchführung des Verfahrens gerichtet sowie auf ein Computerprogrammprodukt mit Steuerbefehlen, welche das Verfahren ausführen.

    摘要： System, methods and apparatus are described that facilitate transmission of data over a multi-wire data communications link, particularly between two devices within an electronic apparatus. A data payload may be converted to a set of transition numbers, the transition numbers may be converted to a sequence of symbols and an error correction code (ECC) may be calculated from symbols in the sequence of symbols. The ECC corresponds to the data payload and the ECC may be appended to the data payload such that the set of transition numbers includes transition numbers corresponding to the ECC. The sequence of symbols is then transmitted on a plurality of signal wires. Clock information is encoded in the sequence of symbols. The clock information may be encoded by ensuring that each pair of consecutive symbols in the sequence of symbols includes two symbols that produce different signaling states on the plurality of signal wires.

    摘要： The present invention is related to a method for optimising a coded modulation scheme with a given spectral efficiency for communication over a fading channel represented/identified by B fading gains, whereby B is an integer number expressing the ratio between a code word duration and the duration over which the fading remains constant. The fading gains belong to a B-dimensional space of fading gains. The method comprises the steps of :
    - selecting a coded modulation scheme having a coding rate, R c , and comprising a mapping with a modulation rate, R m , in accordance with the spectral efficiency,
    - choosing a constellation in accordance with the modulation rate, R m ,
    - labelling the constellation,
    - selecting an error-correcting code type represented by a plurality of code parameters,
    - determining the code parameters in accordance with the coding rate, R c , so that a code performance measure is optimized in the B-dimensional space of fading gains in one or more fading points corresponding to one or more fading points on a predetermined lower bound, at least one of said fading points having at least two different components, whereby at least one specific instance of error-correcting code of said code type is obtained.

    摘要： A communication system including a transmitter (1'), a receiver (2'), and a serial link, in which encoded data (e.g., encoded video data and encoded auxiliary data) are transmitted from the transmitter (1') to the receiver (2'). The serial link can but need not be a TMDS or TMDS-like link. In typical embodiments, alternating bursts of encoded video data and auxiliary data are transmitted over each of one or more channels of the link. Other aspects of the invention are transmitters for use in encoding data for transmission over a serial link, receivers for receiving such data, and methods for sending encoded data over a serial link. In accordance with the invention, source data to be transmitted are encoded using a subset of a full set of code words. The subset consist of preferred code words. The preferred words are predetermined such that each encoded data stream (comprising only preferred words) transmitted over a serial link has a bit pattern that is less susceptible to inter-symbol interference ("ISI") during transmission than is the bit pattern determined by a conventionally encoded version of the same data (comprising not only preferred words but also other members of the full set). Disjoint clusters of code words in the full set are predetermined. Each cluster includes one or more of the preferred words, and optionally also at least one additional code word that is similar to a preferred word of the cluster in the sense that is likely to be generated as a result of probable bit errors in transmission, or transmission and decoding, of such preferred word. In some embodiments, the preferred words have serial bit patterns (during transmission) that have fewer contiguous zeros and ones (and thus are less susceptible to ISI during transmission) than do code words in the full set that are not preferred words.

    摘要： Apparatus and method for decoding of a trellis code applicable to a recording/reproducing apparatus, like e.g. an AIT2 (Advanced Intelligent Tape System 2) tape streamer system. The trellis code has no DC component and no Nyquist frequency component. For encoding, a code word is generated according to a finite state transition chart wherein the cumulative DC electric charges (RDS) and cumulative AC electric charges (ADS) of the code series are set to finite values. The trellis code word, which has been NRZI-modulated, can be decoded without referring to its tail code (bit) and without referring to its head code (bit), when the above-mentioned trellis code word cannot take the start point at a plurality of states.

    摘要： Multi-dimensional space gray maps for multi-dimensional phase modulation as applied to LDPC (Low Density Parity Check) coded modulation. A novel approach is provided within LDPC coded modulation communication systems that employ multi-dimensional phase modulation, using m -D (multi-dimensional) Gray code maps, to provide for improved performance when compared to communication systems employing 1-D (single-dimensional) Gray code maps. This approach can generate all possible m -D Gray code maps for a 2 m -D M PSK modulation system. For example, all of the 2-D Gray code maps may be generated for a communication system using 4-D 8 PSK modulation system (where m =2, and M =8). A variety decoding processing approaches may be employed to perform LDPC coded modulation decoding of multi-dimensional space Gray code mapped signals. The slightly increased decoding complexity (when compared to decoding 1-D Gray code mapped signals) is the computation of symbol metrics and their decomposition to bit metrics.
