The code-rate is hence a real number. A low code-rate close to zero implies a strong code that uses many redundant bits to achieve a good performance, while a large code-rate close to 1 implies a weak code. The redundant bits that protect the information have to be transferred using the same communication resources that they are trying to protect.
HRESULT. HRESULT is a computer programming data type that represents the completion status of a function . It is used in the source code of applications targeting Microsoft Windows and earlier IBM/Microsoft OS/2 operating systems, but its design does not limit its use to these environments; it can be used in any system supporting 32-bit integers .
To eliminate this source of error, Martin Porter released an official free software (mostly BSD-licensed) implementation [2] of the algorithm around the year 2000. He extended this work over the next few years by building Snowball , a framework for writing stemming algorithms, and implemented an improved English stemmer together with stemmers ...
4B5B. In telecommunication, 4B5B is a form of data communications line code. 4B5B maps groups of 4 bits of data onto groups of 5 bits for transmission. These 5-bit words are predetermined in a dictionary and they are chosen to ensure that there will be sufficient transitions in the line state to produce a self-clocking signal.
Decoding methods. In coding theory, decoding is the process of translating received messages into codewords of a given code. There have been many common methods of mapping messages to codewords. These are often used to recover messages sent over a noisy channel, such as a binary symmetric channel .
A Viterbi decoder uses the Viterbi algorithm for decoding a bitstream that has been encoded using a convolutional code or trellis code . There are other algorithms for decoding a convolutionally encoded stream (for example, the Fano algorithm ). The Viterbi algorithm is the most resource-consuming, but it does the maximum likelihood decoding.
In the C programming language, an escape sequence is specially delimited text in a character or string literal that represents one or more other characters to the compiler. It allows a programmer to specify characters that are otherwise difficult or impossible to specify in a literal. An escape sequence starts with a backslash ( \) called the ...
Quoted-Printable, or QP encoding, is a binary-to-text encoding system using printable ASCII characters ( alphanumeric and the equals sign =) to transmit 8-bit data over a 7-bit data path or, generally, over a medium which is not 8-bit clean. Historically, because of the wide range of systems and protocols that could be used to transfer messages ...
