  2. Dynamic frequency selection - Wikipedia

    en.wikipedia.org/wiki/Dynamic_frequency_selection

    Dynamic Frequency Selection (DFS) is a channel allocation scheme specified for wireless LANs, commonly known as Wi-Fi. It is designed to prevent electromagnetic interference by avoiding co-channel operation with systems that predated Wi-Fi, such as military radar , satellite communication , and weather radar , and also to provide on aggregate a ...

  3. 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 ...

  4. Dependent component analysis - Wikipedia

    en.wikipedia.org/wiki/Dependent_component_analysis

    Dependent component analysis (DCA) is a blind signal separation (BSS) method and an extension of Independent component analysis (ICA). ICA is the separating of mixed signals to individual signals without knowing anything about source signals.

  5. 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.

  6. Comparison of audio coding formats - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_audio_coding...

    The 'Music' category is merely a guideline on commercialized uses of a particular format, not a technical assessment of its capabilities. For example, MP3 and AAC dominate the personal audio market in terms of market share, though many other formats are comparably well suited to fill this role from a purely technical standpoint.

  7. Direct coupling analysis - Wikipedia

    en.wikipedia.org/wiki/Direct_coupling_analysis

    Direct coupling analysis or DCA is an umbrella term comprising several methods for analyzing sequence data in computational biology. [1] The common idea of these methods is to use statistical modeling to quantify the strength of the direct relationship between two positions of a biological sequence , excluding effects from other positions.

    In statistical quality control, the individual/moving-range chart is a type of control chart used to monitor variables data from a business or industrial process for which it is impractical to use rational subgroups. [1] The chart is necessary in the following situations: [2]: 231
