Abstract
The present disclosure describes a method and system of tone ordering for discrete multi-tone (DMT) systems with tone grouping. Some illustrative embodiments may include a method, comprising, dividing a plurality of sub-channels within a discrete multi-tone symbol into a plurality of groups, selecting each sub-channel of the plurality of sub-channels in non-sequential sub-channel order from the plurality of groups, and assigning data bits in bit order to each sub-channel in the order in which each sub-channel is selected. Each group comprises an equal number of sub-channels, and each sub-channel comprises a frequency bin with a unique center frequency.
Claims23
A method, comprising:
- dividing a plurality of sub-channels within a discrete multi-tone symbol into a plurality of groups, each group comprising an equal number of sub-channels, and each sub-channel comprising a frequency bin with a unique center frequency;
- selecting each sub-channel of the plurality of sub-channels in non-sequential sub-channel order from the plurality of groups;
- and
- assigning data bits in bit order to each sub-channel in the order in which each sub-channel is selected.
A communication system, comprising:
- a processor that executes software;
- a discrete multi-tone (DMT) receiver, coupled to and configurable by the processor;
- a memory coupled to the processor;
- and
- a group tone order table stored in the memory, each group within the group tone order table comprising an equal number of DMT sub-channels each with a unique center frequency;
- wherein the software selects a sub-channel in non-sequential order with respect to an adjacent sub-channel;
- and
- wherein the software assigns data bits in bit order to the sub-channel in the order in which the sub-channel is selected.
A storage medium containing software that can be executed on a processor within a communication system and that causes the processor to:
- divide a plurality of sub-channels within a discrete multi-tone signal into a plurality of groups of sub-channels, each sub-channel comprising a frequency bin with a unique center frequency;
- select sub-channels from the plurality of sub-channels in non-sequential sub-channel order from the plurality of groups;
- and
- assign data bits in bit order to the sub-channels in the order in which the sub-channels are selected.
