Abstract:
1. A channel equalizer, comprising: a feed forward filter including a plurality of serially-connected filter cells; and a switching unit receiving a signal input to the channel equalizer and an output signal from the feed forward filter via a feedback path, and supplying an output signal as an input to the feed forward filter, wherein the plurality of serially-connected filter cells is embodied as a shift register, wherein the switching unit is configured to receive a control signal, the switching unit supplies, based on receipt of the control signal in a first state, the output signal of the feed forward filter via a feedback path as an input to the feed forward filter, if the output signal of the channel equalizer does not converge, else the switching unit supplies, based on receipt of the control signal in a second state, signals excluding a training sequence from signals that compose the input signal to the channel equalizer, as an input to the feed forward filter.
