    摘要: The present invention relates to apparatus for decoding a sequence of pseudo-ternary digital signals (100), wherein each signal can have one of three possible values, a zero value, a positive value or a negative value. The apparatus is of the type which comprises storage means (116) for storing an estimator (E) representing each of the possible positive and negative values, sampling means (102) for sampling the sequence of signals (100) at predetermined time intervals and obtaining sample signals (S), and comparison means (94, 112) for comparing each sample signal (S) with the estimator (E) to determine whether each sample signal (S) is equivalent to any one of the possible values. Apparatus in accordance with the invention is characterised in that the comparison means comprises estimator changing means (114) for changing the current amplitude of the estimator (E) to the amplitude of a sample signal (S) when the amplitude of the sample signal appears to represent one of the possible positive or negative values more accurately than the current amplitude of the estimator. The invention also relates to a method of decoding a sequence of pseudo-ternary digital signals, wherein each signal can have one of three possible values, a zero value, a positive value or a negative value, utilising apparatus as defined above.

    摘要: The system uses a 3B2T line code, i.e. one in which sets of three or triplets of binary digits are converted into pairs or duplets of ternary elements. All nine of the possible ternary duplets are used, in such a way that the same ternary duplet does not occur twice consecutively. This is done in one version by using the ninth duplet 00 as a repeat indicator, and in the other version by a conversion process in which each conversion operation takes into account the result of the preceding operation.

    摘要: A battery management system comprises a first and second battery cell controllers and a transmission line providing a point-to-point signal transmission path between the first and second battery cell controllers. At least one of the first and second battery cell controllers includes a logic circuit constructed and arranged for encoding data for transmission as a serial data stream along the signal transmission path in compliance with a multi-level encoding technique. The logic circuit comprises an encoding/decoding circuit that generates a modulated signal of the serial data stream over at least three discrete signal levels at a predetermined and fixed data pulse frequency for transmission through the transmission line and encodes a plurality of data units of the serial data stream into a data packet. The data packet includes at least three symbols constructed and arranged with at least four consecutive transmissions per symbol. Each transmission of each symbol assumes one of the three discrete signal levels. At least one transceiver is configured in a transmit mode or a receive mode and that discards any combinations of the maximum number of possible combinations to reduce a source of electromagnetic interference (EMI) on the transmission line.
