Software for error-correcting codes. Simulating the behaviour of error-correcting codes (ECCs) in software is a common practice to design, validate and improve ECCs. The upcoming wireless 5G standard raises a new range of applications for the software ECCs: the Cloud Radio Access Networks (C-RAN) in a Software-defined radio (SDR) context. The ...

The Raytheon Company was founded in 1922 in Cambridge, Massachusetts, by Laurence K. Marshall, Vannevar Bush, and Charles G. Smith as the American Appliance Company. [13] Its focus, which was originally on new refrigeration technology, soon shifted to electronics. The company's first product was a gaseous ( helium) rectifier that was based on ...
The first element of a CIRC decoder is a relatively weak inner (32,28) Reed–Solomon code, shortened from a (255,251) code with 8-bit symbols. This code can correct up to 2 byte errors per 32-byte block. More importantly, it flags as erasures any uncorrectable blocks, i.e., blocks with more than 2 byte errors.
Margaret Elaine Hamilton ( née Heafield; born August 17, 1936) is an American computer scientist. She was director of the Software Engineering Division of the MIT Instrumentation Laboratory, which developed on-board flight software for NASA 's Apollo program. She later founded two software companies—Higher Order Software in 1976 and Hamilton ...
List of ray tracing software. Ray tracing is a technique that can generate near photo-realistic computer images. A wide range of free software and commercial software is available for producing these images. This article lists notable ray-tracing software. Software.
Cyclic redundancy check. A cyclic redundancy check ( CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data. [1] [2] Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents.
Convolutional codes are processed on a bit-by-bit basis. They are particularly suitable for implementation in hardware, and the Viterbi decoder allows optimal decoding. Block codes are processed on a block-by-block basis. Early examples of block codes are repetition codes, Hamming codes and multidimensional parity-check codes.
An irreducible code is a cyclic code in which the code, as an ideal is irreducible, i.e. is minimal in , so that its check polynomial is an irreducible polynomial. Examples [ edit ] For example, if A = F 2 {\displaystyle A=\mathbb {F} _{2}} and n = 3 {\displaystyle n=3} , the set of codewords contained in cyclic code generated by ( 1 , 1 , 0 ...
On-board diagnostics. Various angles and details of a "MaxScan OE509" – a fairly typical onboard diagnostics (OBD) handheld scanner from the first decade of the 21st century. Used to connect to the SAE J1962 Data Link Connector (DLC) found in many cars of the era. On-board diagnostics ( OBD) is a term referring to a vehicle's self-diagnostic ...
