Description
Methods and apparatus for use in a communication channel receiver for generating a Sampling phase error Signal for adjustment of a Sampling clock signal associated with the receiver are provided. In an illustrative embodiment, a method includes generating a Signal representative of a weighted linear combination of a predetermined number of Samples of a received input signal. The combination is a function of the Samples and tap-weights of a finite impulse response filter associated with the receiver. Next, the illus trative method includes generating an error Signal represen tative of the difference between an equalized Sequence of Samples of the received input signal and a decoded Sequence of Samples of the received input Signal. Still further, the illustrative method includes multiplying the weighted linear combination Signal with the error Signal to generate a phase error Signal. The phase error Signal is …
