Method of adaptively controlling the pre-cursor coefficient in a transmit equalizer
A circuit and method for controlling a pre-cursor coefficient in an equalizer of a transmitter device. An input signal from the transmitter is converted into a data signal that includes data symbols transmitted in successive unit intervals. An error signal is formed by comparing the input signal to...

| Zusammenfassung: | A circuit and method for controlling a pre-cursor coefficient in an equalizer of a transmitter device. An input signal from the transmitter is converted into a data signal that includes data symbols transmitted in successive unit intervals. An error signal is formed by comparing the input signal to a threshold value. A determination is made whether to adjust the pre-cursor coefficient, by correlating a sample of the error signal with samples of the data signal from one unit interval earlier and two unit intervals earlier. |
