Patent ID: 7577203

Claim:
A method for minimizing the effect of non-deterministic noise during an idle condition of a serial data link in an information handling system, said method comprising the steps of: a) detecting a non-deterministic noise signal of a serial data link; b) comparing the non-deterministic noise signal to a noise threshold signal, wherein: b1) if the non-deterministic noise signal is less than the noise threshold signal, then keeping the serial data link in an electrical idle state, and b2) if the non-deterministic noise signal is greater than or equal to the noise threshold signal, then b2a) decomposing the non-deterministic noise signal in a time domain, b2b) decomposing the non-deterministic noise signal in a frequency domain, b2c) determining a level of adaptive filtration for the time domain decomposed non-deterministic noise signal, and b2d) determining equalizer tap settings for the frequency domain decomposed non-deterministic noise signal; c) generating an output signal from the adaptively filtered time domain decomposed non-deterministic noise signal and the tap equalized frequency domain decomposed non-deterministic noise signal; d) comparing the output signal to the non-deterministic noise signal, wherein: d1) if the output signal is less than the non-deterministic noise signal, then keeping the serial data link in the electrical idle state, and d2) if the output signal is greater than or equal to the non-deterministic noise signal, then repeating steps b2a, b2b, b2c, b2d, c, d, d1 and d2; wherein each of the steps is performed in the information handling system.
