Abstract
A method that accomplishes margin equalization utilizing tone ordering is provided. The method includes measuring a respective signal-to-noise-ratio (SNR) margin for each respective tone in a multicarrier channel. A plurality of tone groups is determined by, for each tone group, grouping at least one tone with a relatively high SNR margin with at least one tone with a relatively low SNR margin to form a tone group. Ordering information describing the plurality of tone groups is communicated to a transmitter. The transmitter is configured to load bits for transmission by way of the tones based at least on the ordering information.
Claims21
A method, comprising:
- measuring a respective signal-to-noise-ratio (SNR) margin for each respective tone in a multicarrier channel;
- determining a plurality of tone groups by, for each tone group, grouping at least one tone with a relatively high SNR margin with at least one tone with a relatively low SNR margin to form a tone group;
- and
- communicating ordering information describing the plurality of tone groups to a transmitter, wherein the transmitter is configured to load bits for transmission by way of the tones based at least on the ordering information.
A transceiver, comprising:
- a receiver comprising determination circuitry configured to:
- measure a respective signal-to-noise-ratio (SNR) margin for each respective tone in a multicarrier channel;
- determine a plurality of tone groups by, for each tone group, grouping at least one tone with a relatively high SNR margin with at least one tone with a relatively low SNR margin to form a tone group;
- and
- a transmitter configured to transmit tone ordering information describing the plurality of tone groups to a second transceiver, wherein the second transceiver is configured to load bits for transmission to the receiver based at least on the ordering information.
Computer readable media having computer-executable instructions stored thereon that, when executed by a processor, cause the processor to perform corresponding functions, the instructions comprising instructions for:
- measuring a respective signal-to-noise-ratio (SNR) margin for each respective tone in a multicarrier channel;
- determining a plurality of tone groups by, for each tone group, grouping at least one tone with a relatively high SNR margin with at least one tone with a relatively low SNR margin to form a tone group;
- and
- communicating ordering information describing the plurality of tone groups to a transmitter, wherein the transmitter is configured to load bits for transmission by way of the tones based at least on the ordering information.
