error-detection code
51Forward Error Correction — Vorwärtsfehlerkorrektur (kurz FEC von engl. forward error correction, manchmal auch EDAC, für engl. error detection and correction) ist eine Technik, die dazu dient, die Fehlerrate bei der Speicherung oder der Übertragung digitaler Daten zu… …
52Systematic code — In coding theory, a systematic code is one in which the input data are embedded in the encoded output. Similarly, a non systematic code is one in which the output does not contain the input bits. Such codes are used to add redundant information… …
53Hamming code — A forward error correction technique used to detect and correct single bit errors during transmission. The Hamming code adds three verification bits to the end of each four bits of data. The receiving device performs a similar process to… …
54Linear code — In mathematics and information theory, a linear code is an important type of block code used in error correction and detection schemes. Linear codes allow for more efficient encoding and decoding algorithms than other codes (cf. syndrome… …
55Space–time block code — This article deals with coherent space–time block codes (STBCs). For differential space–time block codes, see differential space–time codes.Space–time block coding is a technique used in wireless communications to transmit multiple copies of a… …
56Face detection — is a computer technology that determines the locations and sizes of human faces in arbitrary (digital) images. It detects facial features and ignores anything else, such as buildings, trees and bodies. Definition and relation to other tasks Face… …
57Repetition code — is an (r,1) coding scheme that repeats the bits across a channel to achieve error free communication (r is the number of bits in each codeword for each data bit to be coded). Repetition code is generally a very naive method of encoding data… …
58Corner detection — Feature detection Output of a typical corner detection algorithm …
59Morse code — Chart of the Morse code letters and numerals Morse code is a method of transmitting textual information as a series of on off tones, lights, or clicks that can …
60Self-modifying code — In computer science, self modifying code is code that alters its own instructions, intentionally or otherwise, while it is executing.Self modifying code is quite straightforward to write when using assembly language (taking into account the CPU… …
