  2. Tanner graph - Wikipedia

    en.wikipedia.org/wiki/Tanner_graph

    Tanner proved the following bounds Let be the rate of the resulting linear code, let the degree of the digit nodes be and the degree of the subcode nodes be .If each subcode node is associated with a linear code (n,k) with rate r = k/n, then the rate of the code is bounded by

  3. Low-density parity-check code - Wikipedia

    en.wikipedia.org/wiki/Low-density_parity-check_code

    Below is a graph fragment of an example LDPC code using Forney's factor graph notation. In this graph, n variable nodes in the top of the graph are connected to (n−k) constraint nodes in the bottom of the graph. This is a popular way of graphically representing an (n, k) LDPC code.

  4. Tanner scale - Wikipedia

    en.wikipedia.org/wiki/Tanner_scale

    The Tanner scale (also known as the Tanner stages or sexual maturity rating (SMR)) is a scale of physical development as pre-pubescent children transition into adolescence, and then adulthood. The scale defines physical measurements of development based on external primary and secondary sex characteristics , such as the size of the breasts ...

  5. Bipartite graph - Wikipedia

    en.wikipedia.org/wiki/Bipartite_graph

    A Tanner graph is a bipartite graph in which the vertices on one side of the bipartition represent digits of a codeword, and the vertices on the other side represent combinations of digits that are expected to sum to zero in a codeword without errors. [40] A factor graph is a closely related belief network used for probabilistic decoding of ...

  6. Zemor's decoding algorithm - Wikipedia

    en.wikipedia.org/wiki/Zemor's_decoding_algorithm

    Zemor's algorithm is based on a type of expander graphs called Tanner graph. The construction of code was first proposed by Tanner. [ 3 ] The codes are based on double cover d {\displaystyle d} , regular expander G {\displaystyle G} , which is a bipartite graph.

    Since the source is only 4 bits then there are only 16 possible transmitted words. Included is the eight-bit value if an extra parity bit is used (see Hamming(7,4) code with an additional parity bit).

  9. Functional response - Wikipedia

    en.wikipedia.org/wiki/Functional_response

    A functional response in ecology is the intake rate of a consumer as a function of food density (the amount of food available in a given ecotope).It is associated with the numerical response, which is the reproduction rate of a consumer as a function of food density.
