Abstract
Embodiments enable quick PHY re-training when the link is restarted due an event such as EMI, for example. In particular, embodiments recognize that, in the case of such events as EMI, a substantial portion of the training process as prescribed in the standard can be bypassed during the link restart without affecting subsequent link performance. In particular, embodiments recognize that a substantial amount of previously learned link parameters may still be used after link restart, and thus eliminate the need to re-learn them thereby speeding up the link restart process. Further, embodiments recognize that the standard prescribed link start up procedure can be accelerated in the case of link restart by reducing standard prescribed periods for transitioning between states of the link start up process. Additionally, embodiments provide a mechanism that relies on the auxiliary bit (AUX) of LDPC coded user data frames to pre-emptively and dynamically notch out troublesome EMIs before they cause the link to fail.
