Patent ID: 8054907

Claim:
A method of removing the effect of intersymbol interference (ISI) from a data record indicating times of logic level transitions exhibited by a data signal that has been distorted by ISI exhibited by a system having a particular step response, the method comprising: determining the step response and a step response length of the system exhibiting ISI; determining a set of time defect values based on two or more possible input transition patterns and based at least in part on the step response and the step response length; receiving the data record with a receiver of the system; selecting a transition from within the data record for removal of ISI; inspecting preceding transitions within the data record; obtaining a current time defect, based at least in part upon the inspected preceding transitions and based at least in part on the set of time defect values; and adjusting the data record, based upon the current time defect, to indicate a new time of transition for the selected transition, thereby removing the effect of ISI for the selected transition.
