52Concatenated error correction code — In coding theory, concatenated codes form a class of error correcting codes that are derived by combining an inner code and an outer code. They were conceived in 1966 by Dave Forney as a solution to the problem of finding a code that has both… …
53Noisy-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)… …
54Repetition 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… …
55Low-density parity-check code — In information theory, a low density parity check code (LDPC code) is an error correcting code, a method of transmitting a message over a noisy transmission channel. [David J.C. MacKay (2003) Information theory, inference and learning algorithms …
56Block code — In computer science, a block code is a type of channel coding. It adds redundancy to a message so that, at the receiver, one can decode with minimal (theoretically zero) errors, provided that the information rate (amount of transported… …
57Line code — An example of coding a binary signal using rectangular pulse amplitude modulation with polar non return to zero code …
58Space–time code — A space ndash;time code (STC) is a method employed to improve the reliability of data transmission in wireless communication systems using multiple transmit antennas. STCs rely on transmitting multiple, redundant copies of a data stream to the… …
59VAT-free imports from the Channel Islands — Many low valued exports of goods from the Channel Islands to the United Kingdom are exempt from value added tax (VAT) due to the operation of an EU tax relief called Low Value Consignment Relief (LVCR). LVCR is not limited to the Channel Islands… …
60Multi-carrier code division multiple access — (MC CDMA) is a multiple access scheme used in OFDM based telecommunication systems, allowing the system to support multiple users at the same time. MC CDMA spreads each user symbol in the frequency domain. That is, each user symbol is carried… …
