  2. Channel allocation schemes - Wikipedia

    en.wikipedia.org/wiki/Channel_allocation_schemes

    In Fixed Channel Allocation or Fixed Channel Assignment (FCA) each cell is given a predetermined set of frequency channels. FCA requires manual frequency planning, which is an arduous task in time-division multiple access (TDMA) and frequency-division multiple access (FDMA) based systems since such systems are highly sensitive to co-channel interference from nearby cells that are reusing the ...

  3. Discrete Fourier series - Wikipedia

    en.wikipedia.org/wiki/Discrete_Fourier_series

    The result of the series is also a function of the discrete variable, i.e. a discrete sequence. A Fourier series, by nature, has a discrete set of components with a discrete set of coefficients, also a discrete sequence. So a DFS is a representation of one sequence in terms of another sequence.

    A simple alternative to the above algorithm uses chain decompositions, which are special ear decompositions depending on DFS-trees. [3] Chain decompositions can be computed in linear time by this traversing rule. Let C be a chain decomposition of G. Then G is 2-vertex-connected if and only if G has minimum degree 2 and C 1 is the only cycle in C.

  5. Divide-and-conquer algorithm - Wikipedia

    For example, when a) the work of splitting the problem and combining the partial solutions take time, where is the input size and is some constant; b) when <, the algorithm takes time upper-bounded by , and c) there are subproblems where each subproblem has size ~ . Then, the running times are as follows:

  6. Directional component analysis - Wikipedia

    en.wikipedia.org/wiki/Directional_component_analysis

    DCA is a function of the covariance matrix and a vector direction (the gradient of the impact function), and the first DCA pattern is defined so as to maximise probability density for a given value of the impact metric; As a result, for unit vector spatial patterns:

  7. C standard library - Wikipedia

    en.wikipedia.org/wiki/C_standard_library

    Some compilers (for example, GCC [8]) provide built-in versions of many of the functions in the C standard library; that is, the implementations of the functions are written into the compiled object file, and the program calls the built-in versions instead of the functions in the C library shared object file.

  8. Deterministic finite automaton - Wikipedia

    en.wikipedia.org/wiki/Deterministic_finite_automaton

    An example of a deterministic finite automaton that accepts only binary numbers that are multiples of 3. The state S 0 is both the start state and an accept state. For example, the string "1001" leads to the state sequence S 0, S 1, S 2, S 1, S 0, and is hence accepted.

    Otherwise choose a column c (deterministically). Choose a row r such that A r, c = 1 (nondeterministically). Include row r in the partial solution. For each column j such that A r, j = 1, for each row i such that A i, j = 1, delete row i from matrix A. delete column j from matrix A. Repeat this algorithm recursively on the reduced matrix A.
