Code word (communication) In communication, a code word is an element of a standardized code or protocol. Each code word is assembled in accordance with the specific rules of the code and assigned a unique meaning. Code words are typically used for reasons of reliability, clarity, brevity, or secrecy.
The codes' procedure words, a type of voice procedure, are designed to convey complex information with a few words. American/NATO codes. This is a list of American standardized brevity code words. The scope is limited to those brevity codes used in multiservice operations and does not include words unique to single service operations. While ...
Countersign (military) In military terminology, a countersign is a sign, word, or any other signal previously agreed upon and required to be exchanged between a picket or guard and anybody approaching his or her post. The term usually encompasses both the sign given by the approaching party as well as the sentry's reply.
A code word is a word or a phrase designed to convey a predetermined meaning to an audience who know the phrase, while remaining inconspicuous to the uninitiated. For example, a public address system may be used to make an announcement asking for "Inspector Sands" to attend a particular area, which staff will recognise as a code word for a fire or bomb threat, and the general public will ignore.
So for a rth order RM code, we have to decode iteratively r+1, times before we arrive at the final received code-word. Also, the values of the message bits are calculated through this scheme; finally we can calculate the codeword by multiplying the message word (just decoded) with the generator matrix.
Shannon–Fano coding. In the field of data compression, Shannon–Fano coding, named after Claude Shannon and Robert Fano, is one of two related techniques for constructing a prefix code based on a set of symbols and their probabilities (estimated or measured). Shannon's method chooses a prefix code where a source symbol. i {\displaystyle i}
A generator matrix for a linear [,,]-code has format , where n is the length of a codeword, k is the number of information bits (the dimension of C as a vector subspace), d is the minimum distance of the code, and q is size of the finite field, that is, the number of symbols in the alphabet (thus, q = 2 indicates a binary code, etc.).
Hexspeak. Hexspeak is a novelty form of variant English spelling using the hexadecimal digits. Created by programmers as memorable magic numbers, hexspeak words can serve as a clear and unique identifier with which to mark memory or data. Hexadecimal notation represents numbers using the 16 digits 0123456789ABCDEF.
Commercial code (communications) In telecommunication, a commercial code is a code once used to save on cablegram costs. [1] Telegraph (and telex) charged per word sent, so companies which sent large volumes of telegrams developed codes to save money on tolls. Elaborate commercial codes which encoded complete phrases into single words were ...
Space–time block coding based transmit diversity ( STTD) is a method of transmit diversity used in UMTS third-generation cellular systems. STTD is optional in the UTRAN air interface but mandatory for user equipment ( UE ). STTD utilizes space–time block code (STBC) in order to exploit redundancy in multiple transmitted versions of a signal.
