  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. 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 ...

  4. Placement syntax - Wikipedia

    en.wikipedia.org/wiki/Placement_syntax

    Normally, when an object is created dynamically, an allocation function is invoked in such a way that it will both allocate memory for the object, and initialize the object within the newly allocated memory. The placement syntax allows the programmer to supply additional arguments to the allocation function.

  6. Region-based memory management - Wikipedia

    en.wikipedia.org/wiki/Region-based_memory_management

    e 1 at ρ: Compute the result of the expression e 1 and store it in region ρ; let region ρ in e 2 end: Create a region and bind it to ρ; evaluate e 2; then deallocate the region. Due to this syntactic structure, regions are nested, meaning that if r 2 is created after r 1, it must also be deallocated before r 1; the result is a stack of ...

  7. Allocator (C++) - Wikipedia

    en.wikipedia.org/wiki/Allocator_(C++)

    The custom allocator will serve individual allocation requests by simply returning a pointer to memory from the pool. Actual deallocation of memory can be deferred until the lifetime of the memory pool ends. An example of memory pool-based allocators can be found in the Boost C++ Libraries. [15]

  8. 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.

  9. Depth-first search - Wikipedia

    en.wikipedia.org/wiki/Depth-first_search

    Depth-first search (DFS) is an algorithm for traversing or searching tree or graph data structures. The algorithm starts at the root node (selecting some arbitrary node as the root node in the case of a graph) and explores as far as possible along each branch before backtracking.
