摘要： A method for operating a receiver is disclosed. The receiver may receive, over a channel from a transmitter, a first data bit at a first period of time. The receiver may receive, over the channel, a second data bit at a second period of time subsequent to the first period of time. The first and second data bits each have either a first logical value corresponding to a voltage greater than zero volts or a second logical value corresponding to a voltage less than or equal to zero volts. The receiver performs a coefficient adaptation operation, using the first data bit, to adjust one or more coefficients of a decision feedback equalizer of the receiver only when the logical value of the first data bit is equal to the logical value of the second data bit.
