Abstract
Various embodiments describe communication systems for implementing high-speed transmission systems using waveguide-mode transmission over wires. In certain examples, a communication system uses wire pairs as “waveguides” that transmit data at high frequencies and speeds. The data is transmitted through wave propagation that takes various forms, such as surface waves and Total Internal Reflection (TIR) waves.
Claims23
A device comprising:
- a transmitter coupled to transmit signals to one or more signal-carrying media having waveguide properties and supporting a plurality of waveguide modes, the transmitter having a plurality of antennas that shapes and transmits a first signal into the transmission media;
- and
- at least one coupler coupled between the transmitter and the signal-carrying media, the at least one coupler couples the signals to the signal-carrying media via at least one waveguide mode within the plurality of waveguide modes;
- and
- wherein the signal-carrying media comprises at least one wire, each wire comprising a conductor covered with a dielectric insulator and the first signal propagates at least partially around the at least one wire.
A device for receiving signals comprising:
- a receiver coupled to receive signals from one or more signal-carrying media having waveguide properties and supporting a plurality of waveguide modes, the receiver having a plurality of antennas that receives a first signal from the transmission media;
- and
- at least one coupler coupled between the receiver and the signal-carrying media, the at least one coupler couples the signals from the signal-carrying media via at least one waveguide mode within the plurality of waveguide modes;
- and
- wherein the signal-carrying media comprises at least one wire, each wire comprising a conductor covered with a dielectric insulator, the first signal being communicated around the at least one wire.
A method for training a system that communicates signals using at least one waveguide mode, the method comprising:
- sending probing sequences to at least one receiver, covering at least one candidate sub-carrier frequency on each of a plurality of data transmission channels, each of the plurality of data transmission channels being coupled to a transmission antenna and a receiving antenna;
- for each of the plurality of data transmission channels, receiving a channel response feedback from the at least one receiver on at least one candidate sub-carrier frequency;
- estimating channel responses for at least one data transmission channel;
- in the case of more than one data transmission channels, estimating crosstalk responses between at least one of the pairs of the plurality of data transmission channels;
- based on the estimated channel responses and crosstalk responses, identifying at least one sub-carrier frequency for each data transmission channel;
- and
- for each data transmission channel, selecting one of the identified sub-carrier frequencies as a preferred sub-carrier frequency for transmitting data.
