摘要： The invention relates to a method and a device for carrying out error treatment during transmission of coded data in the form of at least one data word via a communication system (900, 901, 902). According to the invention, a code word is selected for the at least one data word using a predetermined coding rule. The data are represented as bits that can take two different values, one or zero. At least one current digital sum is produced in such a manner that a summed up difference of the total of ones and the total of zeros is produced at least for the code data word (907) and that this current digital sum is transmitted (901), whereby the current digital sum for the subsequent code data word is determined and compared with the one transmitted. If there is a deviation, an error is detected.

摘要： A data storage channel encoder (150) includes a data word input (152), a code word output (153) and an encoder. The encoder (150) is coupled between the data word input (152) and the code word output (153) and is adapted to encode successive data words (Xm) received on the data word input (152) into sucessive code words (Yn) on the code word output (153) according to a selected code having combined maximum transition run and parity constraints. The maximum transition run constraint constrains the successive code words (Yn) such that, when the successive code words (Yn) are concatenated to form an encoded bit stream (260), the encoded bit stream (260) has a maximum of one consecutive transition beginning at either odd or even indexed bit positions (268) in the encoded bit stream (260) and a maximum of two consecutive transitions beginning at the other of the odd or even indexed bit positions (268).

摘要： An encoder/decoder is disclosed which is operative to convert an 8 bit value (102a) to a ten bit serial run length limited code (141a) for transmission over a serial data link. The encoding technique maintains DC balance within 2 bits over a single ten bit word and compensates for DC imbalance by inverting selected words (156a) in the transmission sequence to correct for a DC imbalance resulting from the transmission of a prior unbalanced word. One or more encoding lookup tables (150a-150d) are employed at the encoder to map each byte into a ten bit run length limited code for serialization and transmission over the serial data link. A second decoding lookup table is employed at the decoder to map the received ten bit run length limited code into the original 8 bit value.

摘要： The present invention uses a conversion table a part of which is duplexed in order to directly convert input M-bit data into an N-bit code without using a margin bit. This conversion table comprises first and second sub-tables each including a plurality of code groups, and these code groups contain different codes to the same input data. In the second sub-table, a part of the first sub-table obtaining by allocating different codes to the data ranging from the first input data to the second input data of the sub-table is duplexed. The set of the codes of the duplexed portion of the conversion table is so constituted as to take a digital sum variation of opposite signs, and codes are sequentially allocated to the input data from the code having the greater absolute value of the digital sum variation. In this way, the present invention can appropriately suppress low frequency components of modulation signals.

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 invention relates to method and apparatus for improving the performance of communication systems using Run Length Limited (RLL) messages such as the existing Automatic Identification System (AlS). A binary data sequence is Forward Error Correction (FEC) coded and then the sequence is compensated, for example by bit-erasure, so that either bit-stuffing is not required, or a bit stuffer will not be activated to ensure that the coded sequence meets the RLL requirement. Various embodiments are described to handle different architectures or input points for the FEC encoder and bit erasure module. The bit erasure module may also add dummy bits to ensure a RLL compliant CRC or to selectively add bits to a reserve buffer to compensate for later bit stuffing in a header. Additional RLL training sequences may also be added to assist in, receiver acquisition.

摘要： Techniques are disclosed for detecting image depth in three-dimensional (3-D) surface imaging. The disclosed techniques can be used, for example, to provide structured light encoded with a coded word that includes error-correcting code (ECC). The ECC is effectively configured to detect and correct data errors as may result, for example, from the presence of ambient light and/or camera-noise-causing errors during imaging. In an example case, the coded word is a 15-bit pattern provided in a 35 matrix and including: (1) nine data bits of disparity code; (2) five ECC bits for correcting an error and detecting two errors; and (3) one 8-bit/10-bit encoding bit to ensure the presence of a transient pixel in the data for white threshold level detection. Greater or lesser bit quantities and varied bit partitioning matrices can be provided, as desired. In some cases, imaging robustness and/or power usage can be improved using the disclosed techniques.
