  • DECISION FEED FORWARD EQUALIZATION FOR PARTIAL RESPONSE EQUALIZED SIGNAL INCLUDING PRE-CURSOR CANCELATION
    Publication number: 20240340201
    Abstract: A receiver includes a partial response (PR) system that receives a received signal from a transmitter over a channel and equalize the received signal such that there is a controlled relationship between consecutive values of equalized received symbols and transmitted data transmitted by the transmitter. The receiver also includes a decision feed forward equalization (DFFE) system that receives partial response signals from the PR system and cancel at least one of pre-cursor intersymbol interference (ISI) or post-cursor ISI introduced by the channel.
    Type: Application

  • Decision feed forward equalization for partial response equalized signal including pre-cursor cancelation
    Patent number: 12057974
    Abstract: A receiver includes a decision feed forward equalization (DFFE) system that generates, based on a digital signal that includes at least one intersymbol interference (ISI) value introduced by a communication channel, a detected signal including a set of detected symbol values. The DFFE system cancels the at least one ISI value from the detected signal using the set of estimated transmitted symbols and a set of tap coefficients to obtain a compensated signal and a set of compensated symbol values.
