51Block cipher modes of operation — This article is about cryptography. For method of operating , see modus operandi. In cryptography, modes of operation is the procedure of enabling the repeated and secure use of a block cipher under a single key.[1][2] A block cipher by itself… …
52Information theory — Not to be confused with Information science. Information theory is a branch of applied mathematics and electrical engineering involving the quantification of information. Information theory was developed by Claude E. Shannon to find fundamental… …
53Spectral efficiency — Spectral efficiency, spectrum efficiency or bandwidth efficiency refers to the information rate that can be transmitted over a given bandwidth in a specific communication system. It is a measure of how efficiently a limited frequency spectrum is… …
54Convolutional code — In telecommunication, a convolutional code is a type of error correcting code in which each m bit information symbol (each m bit string) to be encoded is transformed into an n bit symbol, where m/n is the code rate (n ≥ m) and the transformation… …
55Mathematics and Physical Sciences — ▪ 2003 Introduction Mathematics Mathematics in 2002 was marked by two discoveries in number theory. The first may have practical implications; the second satisfied a 150 year old curiosity. Computer scientist Manindra Agrawal of the… …
56Cyclic redundancy check — A cyclic redundancy check (CRC) is an error detecting code designed to detect accidental changes to raw computer data, and is commonly used in digital networks and storage devices such as hard disk drives. Blocks of data entering these systems… …
57Code — redirects here. CODE may also refer to Cultural Olympiad Digital Edition. Decoded redirects here. For the television show, see Brad Meltzer s Decoded. For code (computer programming), see source code. For other uses, see Code (disambiguation).… …
58Binary Golay code — In mathematics and computer science, a binary Golay code is a type of error correcting code used in digital communications. The binary Golay code, along with the ternary Golay code, has a particularly deep and interesting connection to the theory …
59Noisy-channel coding theorem — In information theory, the noisy channel coding theorem (sometimes Shannon s theorem), establishes that for any given degree of noise contamination of a communication channel, it is possible to communicate discrete data (digital information)… …
60Fehlerkorrekturverfahren — dienen dazu, Fehler bei der Speicherung und Übertragung von Daten zu erkennen und wenn möglich, zu korrigieren. Fehlererkennungsverfahren beschränken sich auf eine reine Fehlererkennung. Dazu wird vor der Datenspeicherung oder Übertragung den… …
