  2. Time-slot interchange - Wikipedia

    en.wikipedia.org/wiki/Time-Slot_Interchange

    In a time-slot interchange (TSI) switch, two memory accesses are required for each connection (one to read and one to store). Let T be the time to access the memory. Therefore, for a connection, 2T time will be taken to access the memory. If there are n connections and t is the operation time for n lines, then t=2nT which gives n=t/2T

  3. 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 ...

  4. Stored program control - Wikipedia

    en.wikipedia.org/wiki/Stored_program_control

    SPC technology using analog switching matrices was largely phased out in the 1980s and had disappeared from most modern networks by the late 1990s. The addition of time-division multiplexing (TDM) decreased subsystem sizes and dramatically increased the capacity of the telephone network. By the 1980s, SPC technology dominated the ...

  5. Time-division multiplexing - Wikipedia

    en.wikipedia.org/wiki/Time-division_multiplexing

    Time-division multiplexing (TDM) is a method of transmitting and receiving independent signals over a common signal path by means of synchronized switches at each end of the transmission line so that each signal appears on the line only a fraction of time according to agreed rules, e.g. with each transmitter working in turn.

  6. Spatial multiplexing - Wikipedia

    en.wikipedia.org/wiki/Spatial_multiplexing

    Spatial multiplexing or space-division multiplexing (SM, SDM or SMX) is a multiplexing technique in MIMO wireless communication, fiber-optic communication and other communications technologies used to transmit independent channels separated in space.

  7. Time-driven switching - Wikipedia

    en.wikipedia.org/wiki/Time-driven_switching

    In telecommunication and computer networking, time-driven switching (TDS) is a node by node time variant implementation of circuit switching, where the propagating datagram is shorter in space than the distance between source and destination. With TDS it is no longer necessary to own a complete circuit between source and destination, but only ...

  8. Sliding mode control - Wikipedia

    en.wikipedia.org/wiki/Sliding_mode_control

    Instead, it can switch from one continuous structure to another based on the current position in the state space. Hence, sliding mode control is a variable structure control method. The multiple control structures are designed so that trajectories always move toward an adjacent region with a different control structure, and so the ultimate ...
