Abstract
Using a known or later developed time domain equalizer coefficient training algorithm, a least square solution for the time domain equalizer coefficients is taken at a starting point and iteratively improved on. In particular, the improvement is directed towards maximizing number of bits per frame loaded over the time domain equalizer coefficient choice. This can be accomplished by maximizing capacity directly rather than setting a goal to shorten the channel and hoping that the capacity will be maximized as a result.
Claims30
A system that performs supplemental frequency domain training of a time domain equalizer comprising:
- a training module that uses an initial solution for time domain equalizer coefficients and determines updated time domain equalizer coefficients by maximizing the number of bits per frame;
- and
- a time domain equalizer that receives the updated time domain equalizer coefficients.
A method that performs supplemental frequency domain training of the time domain equalizer comprising:
- receiving a solution of initial time domain equalizer coefficients;
- determining updated time domain equalizer coefficients by maximizing the number of bits per frame;
- and
- forwarding the updated time domain equalizer coefficients to a time domain equalizer.
An information storage media comprising information that performs supplemental frequency domain training of the time domain equalizer comprising:
- information that receives a solution of initial time domain equalizer coefficients;
- information that determines updated time domain equalizer coefficients by maximizing the number of bits per frame;
- and
- information that forwards the updated time domain equalizer coefficients to a time domain equalizer.
