Abstract
The present invention provides a receiver including an ADC, an echo-cancellation circuit and a control circuit. In the operations of the receiver, the ADC uses a clock signal to perform an analog-to-digital converting operation on an analog input signal to generate digital input signal, the echo-cancellation circuit refers to a plurality of tap coefficients to perform an echo-cancellation operation on the digital input signal to generate an output signal, and the control circuit is configured to control a phase of the clock signal inputted into the ADC. In addition, when the phase of the clock signal is adjusted, the control circuit calculates a plurality of updated tap coefficients according to the plurality of tap coefficients used by the echo-cancellation circuit in a previous time, for use of the echo-cancellation circuit.
