  2. Tridiagonal matrix algorithm - Wikipedia

    en.wikipedia.org/wiki/Tridiagonal_matrix_algorithm

    In numerical linear algebra, the tridiagonal matrix algorithm, also known as the Thomas algorithm (named after Llewellyn Thomas), is a simplified form of Gaussian elimination that can be used to solve tridiagonal systems of equations.

  3. Time-division multiple access - Wikipedia

    en.wikipedia.org/wiki/Time-division_multiple_access

    TDMA frame structure showing a data stream divided into frames and those frames divided into time slots. Time-division multiple access (TDMA) is a channel access method for shared-medium networks. It allows several users to share the same frequency channel by dividing the signal into different time slots. [1]

  4. Digital AMPS - Wikipedia

    en.wikipedia.org/wiki/Digital_AMPS

    The access method used for IS-54 is Time Division Multiple Access (TDMA), which was the first U.S. digital standard to be developed. It was adopted by the TIA in 1992. TDMA subdivides each of the 30 kHz AMPS channels into three full-rate TDMA channels, each of which is capable of supporting a single voice call.

  5. Self-organized time-division multiple access - Wikipedia

    en.wikipedia.org/wiki/Self-organized_time...

    Time-division multiple access (TDMA) divides a channel into frames, which furthermore are subdivided into a vast number of time slots. Users transmit in rapid succession, one after the other, each using their own time slot. One of the drawbacks of TDMA is that it requires a central station for slot assignment and time synchronization.

  6. Space-division multiple access - Wikipedia

    en.wikipedia.org/wiki/Space-division_multiple_access

    Space-division multiple access (SDMA) is a channel access method based on creating parallel spatial pipes (focused signal beams) using advanced antenna technology next to higher capacity pipes through spatial multiplexing and/or diversity, by which it is able to offer superior performance in radio multiple access communication systems (where multiple users may need to use the communication ...

  7. Low-energy adaptive clustering hierarchy - Wikipedia

    en.wikipedia.org/wiki/Low-energy_adaptive...

    Low-energy adaptive clustering hierarchy ("LEACH") [1] is a TDMA-based MAC protocol which is integrated with clustering and a simple routing protocol in wireless sensor networks (WSNs). The goal of LEACH is to lower the energy consumption required to create and maintain clusters in order to improve the life time of a wireless sensor network.

  8. Multi-frequency time-division multiple access - Wikipedia

    en.wikipedia.org/wiki/Multi-frequency_time...

    MF-TDMA ("Multi-frequency time-division multiple access") is a technology for dynamically sharing bandwidth resources in an over-the-air two-way communications network.
