A demultiplexing apparatus includes a signal receiving unit that receives signals, an analog demultiplexing unit that analog-demultiplexes, in predetermined units of channels, received signals received by the signal receiving unit and generates analog demultiplexed signals, and a plurality of digital demultiplexing units that digital-demultiplex the analog demultiplexed signals in units of sub-channels and generate digital demultiplexed signals. The analog demultiplexing unit controls, concerning the analog demultiplexed signals output to the digital demultiplexing units, a total value of bandwidths in which a signal is present so as to be a predetermined value or less.

A system for transmitting signals includes Orbital Angular Momentum (OAM) processing circuitry for receiving a plurality of input signals and applying a different orbital angular momentum to each of the plurality of input signals for transmission to a second location. Electromagnetic knot processing circuitry receives a plurality of OAM processed signals from the OAM processing circuitry and applies an electromagnetic knot to each of the received OAM processed signal before transmission to the second location. Multiplexing circuitry multiplexes the plurality of OAM/electromagnetic knot processed signals into a single multiplexed OAM/electromagnetic knot processed signal. A first signal degradation caused by environmental factors of the OAM/electromagnetic knot processed signal is improved over a second signal degradation caused by the environmental factors of a signal not including the electromagnetic knot. A transmitter transmits the single multiplexed OAM/electromagnetic knot processed signal to the second location.

A transmitter is set to time division multiple access (TDMA) mode and allocated a first TDMA channel. In the TDMA mode, the additional TDMA channels are allocated to and deallocated from the transmitter, according a traffic demand at the transmitter, until all TDMA channels are assigned and the traffic demand reaches a threshold, whereupon the transmitter is switched to a frequency division multiple access (FDMA) mode, and assigned an FDMA channel. In response to traffic levels, the transmitter is switched to larger bandwidth FDMA channels and, optionally, to a concurrent FDMA-TDMA mode having a large bandwidth FDMA channel in addition to a number of TDMA channels. Optionally, switching the transmitter among TDMA mode, FDMA mode, and concurrent FDMA-TDMA mode is based, at least in part, on QoS, or time of day, or user statistics, or combinations thereof.

A system for transmitting signals includes processing circuitry for receiving at least one input signal for transmission from the processing circuitry to a second location. Electromagnetic knot processing circuitry receives processed signals from the first processing circuitry and applies an electromagnetic knot to the received processed signal before transmission to the second location. A first signal degradation caused by environmental factors of the electromagnetic knot processed signal is improved over a second signal degradation caused by the environmental factors of a non-electromagnetic knot processed signal.
