Abstract:
A method for dynamically reallocating data in a discrete multi-tone communication system having a plurality of bins for sending data, the method comprising the steps of:determining a signal-to-noise value for each of the plurality of bins;defining a current reference signal-to-noise value;defining a projected reference signal-to-noise value;calculating a current signal-to-noise margin for each of the plurality of bins based on the signal-to-noise value and the current reference signal-to-noise value;calculating a projected signal-to-noise margin for each of the plurality of bins based on the signal-to-noise value and the projected reference signal-to-noise value;identifying a first portion of the plurality of bins which have a maximum projected signal-to-noise margin;identifying a second portion of the plurality of bins which have a minimum current signal-to-noise margin; anddynamically determining a first number of bits to be reallocated from the second portion of bins to the first portion of bins.
