Channel bonding with orbital angular momentum
View Patent ↗Different data communication architectures deliver a wide variety of content, including audio and video content, to consumers. The architectures employ channel bonding to deliver more bandwidth than any single communication channel can carry. In some implementations, the communication architectures distribute data across multiple orbital angular momentum channels in the bonded channel group.
1. A system comprising:
a distributor;
an input interface; and
output interfaces to corresponding communication channels that form a bonded channel group, where:
the distributor is in communication with the input interface and the output interfaces;
the distributor is configured to receive source data from the input interface and distribute the source data across at least one of the communication channels; and
the communication channels comprising orbital angular momentum (OAM) channels,
wherein the source data comprises a stream of packets and the distributor is configured to divide the stream of packets into at least one group of packets,
wherein the distributor is configured to transmit the group of packets across at least one corresponding OAM channel of the OAM channels.
2. The system of claim 1 , wherein the distributor is configured to transmit the group of packets across a corresponding plurality of the OAM channels.
3. The system of claim 2 , wherein the distributor is configured to transmit the groups of packets across the at least one corresponding OAM channel in a different group order in relation to other OAM channels.
4. The system of claim 3 , wherein the distributor is configured to transmit the groups of packets across the at least one corresponding OAM channel in a group order that is shifted in relation to the other OAM channels.
5. The system of claim 1 , further comprising a modulator circuit in communication with the distributor and configured to multiplex the source data to the OAM channels using orthogonal frequency-division multiplexing (OFDM).
6. The system of claim 5 , wherein the distributor is configured to apply orbital multiplexing techniques for distributing the source data across the OAM channels.
7. The system of claim 1 , wherein the distributor is configured to determine when to enhance transmission reliability, and in response perform data interleaving on the source data.
8. The system of claim 1 , wherein a first portion of the source data is modulated at a modulation frequency across a first channel of the OAM channels, where the first channel has a first orbital angular momentum and a second portion of the source data is also modulated at the modulation frequency over a second channel of the OAM channels, where the second channel has a second orbital angular momentum.
9. A system comprising:
a distributor;
an input interface; and
output interfaces to corresponding communication channels that form a bonded channel group, where:
the distributor is in communication with the input interface and the output interfaces;
the distributor is configured to receive source data from the input interface and distribute the source data across at least one of the communication channels; and
the communication channels comprising orbital angular momentum (OAM) channels,
wherein the distributor is configured to determine when to accelerate transfer of the source data, and in response, transfer selected packets of the source data across a single OAM channel of the OAM channels without redundancy.
10. A method comprising:
receiving a packet stream;
dividing the packet stream into communication units;
identifying a bonded channel group of communication channels among a set of available communication channels;
distributing the communication units across the bonded channel group, where the communication channels of the bonded channel group have a different orbital state from one another;
transmitting a first group of communication units across a first communication channel in the bonded channel group having a first orbital angular momentum in a first group order, and
transmitting the first group of communication units across a second communication channel in the bonded channel group having a second orbital angular momentum in a second group order, wherein the transmitting of the first group of communication units across the first and second communication channels occurs simultaneously.
11. The method of claim 10 , further comprising multiplexing the communication units across the communication channels using orthogonal frequency-division multiplexing (OFDM).
12. The method of claim 10 , wherein the second group order comprises a shifted version of the first group order.
13. The method of claim 10 , where distributing further comprises: distributing the communication units in a different order to the communication channels in the bonded channel group.
