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.).
This is a list of notable open-source video games. Open-source video games are assembled from and are themselves open-source software, including public domain games with public domain source code. This list also includes games in which the engine is open-source but other data (such as art and music) is under a more restrictive license.
Between 2019 and 2021 K1n9_Duk3 recreated the source code of Commander Keen 4, 5 and 6, based on the already released source code of Catacomb 3-D, Wolfenstein 3-D and Keen Dreams. When compiled with the Borland C++ v3.0 compiler, compressing the newly created executables with LZEXE 100% identical copies of the original v1.4 executables are ...
Hamming (7,4) In coding theory, Hamming (7,4) is a linear error-correcting code that encodes four bits of data into seven bits by adding three parity bits. It is a member of a larger family of Hamming codes, but the term Hamming code often refers to this specific code that Richard W. Hamming introduced in 1950.
Agent Smith (later simply Smith) is a fictional character and the main antagonist of The Matrix franchise.The character was primarily portrayed by Hugo Weaving in the first trilogy of films and voiced by Christopher Corey Smith in The Matrix: Path of Neo (2005), with Ian Bliss and Gideon Emery playing his human form, Bane, in the films and Path of Neo respectively.
The distance of the concatenated code Cout ∘ Cin is at least dD, that is, it is a [ nN, kK, D '] code with D ' ≥ dD . Proof: Consider two different messages m1 ≠ m2 ∈ BK. Let Δ denote the distance between two codewords. Then. Thus, there are at least D positions in which the sequence of N symbols of the codewords Cout ( m1) and Cout ...
Barcode. A UPC-A barcode. A barcode or bar code is a method of representing data in a visual, machine-readable form. Initially, barcodes represented data by varying the widths, spacings and sizes of parallel lines. These barcodes, now commonly referred to as linear or one-dimensional (1D), can be scanned by special optical scanners, called ...
Repeat-accumulate code. In computer science, repeat-accumulate codes ( RA codes) are a low complexity class of error-correcting codes. They were devised so that their ensemble weight distributions are easy to derive. RA codes were introduced by Divsalar et al. In an RA code, an information block of length is repeated times, scrambled by an ...
