Abstract
In the present invention, an ADSL system (10) identifies good bin as a bin capable of successfully transmitting data to a destination. A bad bin is identified as a carrier that is not capable of successfully transmitting data to the destination. A marginal bin is identified as a carrier that may be capable of transmitting data to the destination. The power to a bad bin is reduced and allocated to the marginal or good bin(s) to allow an increased bit rate. In another embodiment, the power to marginal bin is reduced and allocated to the good bin(s).
Claims24
A method for optimizing a data rate of a Discrete Multi-Tone communication system, the method comprising:
- performing a channel analysis on a plurality of bins;
- identifying a bad bin, wherein a bad bin is one of the plurality of bins that does not meet a predefined performance criterion wherein the predefined performance criterion defines whether any data can be transmitted using the bad bin;
- specifying a reduced power to be transmitted over the bad bin;
- and
- specifying an increased power to be transmitted over at least one of the plurality of bins that is not the bad bin.
A method for optimizing a data rate of a Discrete Multi-Tone communication system, the method comprising:
- performing a channel analysis on a plurality of bins;
- identifying a bad bin, wherein a bad bin is one of the plurality of bins that does not meet a first predefined performance criterion wherein the first predefined performance criterion defines whether any data can be transmitted using the bad bin;
- identifying a good bin, wherein a good bin is one of the plurality of bins that meets a second predefined performance criterion;
- reducing a transmit power to the bad bin by a first power amount;
- and
- increasing a transmit power to the good bin by a second power amount.
A method for optimizing a data rate of a Discrete Multi-Tone communication system having a plurality of bins, the method comprising:
- identifying a bad bin, wherein a bad bin is one of the plurality of bins that does not meet a first predefined performance criterion;
- identifying a first good bin, wherein the first good bin is one of the plurality of bins that meets a second predefined performance criterion;
- identifying a marginal bin, wherein a marginal bin is one of the plurality of bins that meets a third predefined performance criterion;
- reducing a transmit power to the bad bin by a first power amount;
- increasing a transmit power to the marginal bin by a second power amount;
- identifying the marginal bin as a second good bin in response to the step of increasing;
- and
- transmitting data on the first good bin and the second good bin.
