  2. Error vector magnitude - Wikipedia

    en.wikipedia.org/wiki/Error_Vector_Magnitude

    The degradation in dynamic EVM is due to the PA transient response affecting the preamble at the start of the packet and causing an imperfect channel estimate. Studies have shown that dynamic EVM with a 50% duty cycle square wave applied to PA Enable to be worse than the static EVM (PA Enable with 100% duty cycle). [4]

  3. Earned value management - Wikipedia

    en.wikipedia.org/wiki/Earned_value_management

    There is a measurement limitation for how precisely EVM can be used, stemming from classic conflict between accuracy and precision, as the mathematics can calculate deceptively far beyond the precision of the measurements of data and the approximation that is the plan estimation.

  4. Budgeted cost of work performed - Wikipedia

    en.wikipedia.org/wiki/Budgeted_cost_of_work...

    Budgeted cost of work performed (BCWP) also called earned value (EV), is the budgeted cost of work that has actually been performed in carrying out a scheduled task during a specific time period. [1] The BCWP is the sum of the budgets for completed work packages and completed portions of open work packages, plus the applicable portion of the ...

  5. Merkle tree - Wikipedia

    en.wikipedia.org/wiki/Merkle_tree

    A hash tree allows efficient and secure verification of the contents of a large data structure. A hash tree is a generalization of a hash list and a hash chain . Demonstrating that a leaf node is a part of a given binary hash tree requires computing a number of hashes proportional to the logarithm of the number of leaf nodes in the tree. [ 1 ]

  9. Butterfly diagram - Wikipedia

    en.wikipedia.org/wiki/Butterfly_diagram

    The name "butterfly" comes from the shape of the data-flow diagram in the radix-2 case, as described below. [1] The earliest occurrence in print of the term is thought to be in a 1969 MIT technical report. [2] [3] The same structure can also be found in the Viterbi algorithm, used for finding the most likely sequence of hidden states.
