  2. OBD-II PIDs - Wikipedia

    en.wikipedia.org/wiki/OBD-II_PIDs

    OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.

  3. Burst error-correcting code - Wikipedia

    en.wikipedia.org/wiki/Burst_error-correcting_code

    Proof. We need to prove that if you add a burst of length to a codeword (i.e. to a polynomial that is divisible by ()), then the result is not going to be a codeword (i.e. the corresponding polynomial is not divisible by ()).

    Error-free code words: aaaabbbbccccddddeeeeffffgggg Interleaved: abcdefgabcdefgabcdefgabcdefg Transmission with a burst error: abcdefgabcd____bcdefgabcdefg Received code words after deinterleaving: aa_abbbbccccdddde_eef_ffg_gg

  5. Key Code Qualifier - Wikipedia

    en.wikipedia.org/wiki/Key_Code_Qualifier

    Key Code Qualifier is an error-code returned by a SCSI device. When a SCSI target device returns a check condition in response to a command , the initiator usually then issues a SCSI Request Sense command .

  6. Error detection and correction - Wikipedia

    en.wikipedia.org/wiki/Error_detection_and_correction

    The on-line textbook: Information Theory, Inference, and Learning Algorithms, by David J.C. MacKay, contains chapters on elementary error-correcting codes; on the theoretical limits of error-correction; and on the latest state-of-the-art error-correcting codes, including low-density parity-check codes, turbo codes, and fountain codes.

  7. List of Boeing customer codes - Wikipedia

    en.wikipedia.org/wiki/List_of_Boeing_customer_codes

    The codes are in the form of two letters and/or digits which are appended to the aircraft's model designator, as seen in the following examples: A Boeing 377-10 ordered by Pan American World Airways with customer code 26 would be designated 377-10-26. [1] [note 1] A Boeing 707-100 ordered by Qantas with customer code 38 would be designated as ...

  8. Block code - Wikipedia

    en.wikipedia.org/wiki/Block_code

    As mentioned above, there are a vast number of error-correcting codes that are actually block codes. The first error-correcting code was the Hamming(7,4) code, developed by Richard W. Hamming in 1950. This code transforms a message consisting of 4 bits into a codeword of 7 bits by adding 3 parity bits. Hence this code is a block code.

  9. Repeat-accumulate code - Wikipedia

    Systematic IRA codes are considered a form of LDPC code. Litigation over whether the DVB-S2 LDPC code is a form of IRA code is ongoing. [ 2 ] US patents 7,116,710; 7,421,032; 7,916,781; and 8,284,833 are at issue.
