Abstract: A transceiver for echo and near-end crosstalk cancellation without a loop timing configuration. The transceiver comprises a receiver, a timing recovery circuit, a same-channel phase interpolator, an echo canceller, a near-channel phase interpolator and a near-end crosstalk (NEXT) canceller. The same-channel phase interpolator and the near-channel phase interpolator receive a phase choosing signal from the timing recovery circuit to determine a specific phase from different phases. The same-channel phase interpolator generates a same-channel phase-modified signal with the specific phase and outputs the phase-modified signal to the echo canceller to cancel an echo in the received signal. The near-channel phase interpolator generates a near-channel phase-modified signal with the specific phase and outputs the near-channel phase-modified signal to the NEXT canceller to cancel a NEXT signal in the received signal.

Abstract: A method for overflow testing of a blind equalizer. The method uses the following steps; providing a primary located signal in a primary signaling point of a period by a signal generating loop; multiplying the primary located signal by a set of continuously decreasing signals to get a primary signal; providing a interfering located signal in a plurality of interfering signaling points of the period by a ISI generating loop, wherein the interfering signaling points are different from the primary signaling point; multiplying the interfering located signal by a set of continuously increasing/decreasing signals to get an interference signal; adding the primary signal and the interference signal to get the input signal; inputting the input signal to the blind equalizer to adapt the input signal, wherein the tap weights corresponding to the interference signal in a blind equalizer overflow.

Abstract: A receiver for baseline wandering compensation. The receiver is capable of correcting for baseline wander and receiving killer packets, and includes an analog-to-digital converter, an equalizer, a slicer and a baseline wander corrector. The analog-to-digital converter is coupled to a transmission channel to receive and digitize input signals and outputs a sample. The equalizer is coupled to the analog-to-digital converter to receive the sample, and outputs an equalized sample. The slicer is coupled to the equalizer to receive the equalized sample, and outputs a symbol based on the equalized sample output from the equalizer. The baseline wander corrector is coupled between the slicer and the equalizer. The baseline wander corrector receives the symbol output from the slicer and the equalized sample output from the equalizer, calculates a baseline correction, and adds the baseline correction to the equalized sample output from the equalizer.

Abstract: A method of adjusting the weights of a blind equalizer. In the blind equalizer, an error signal e(n) is reset to zero as soon as the error signal e(n) reaches a predetermined value such as a maximum error signal value so that the weight vector W(n+1) is unaffected by the error signal e(n). Furthermore, the error signal e(n) is also reset to zero as soon as a second slicer output r2(n) changes from the original value due to an adjustment or transmission error and results in an inaccuracy of error signal e(n) so that the weight vector W(n+1) is unaffected by the error signal e(n).
