摘要： A receiver for echo and crosstalk cancellation includes a level decision module, a digital-to-analog converter (DAC), an analog-to-digital converter (ADC) and a response module. The level decision module determines plural levels and plural level magnitudes according to an estimated signal to generate a first digital signal. The DAC converts the first digital signal into a first analog signal according to the levels and the level magnitudes. The ADC receives a first difference signal between the receiving signal and the first analog signal, and converts the first difference signal into a second digital signal. According to the first digital signal, the response module generates a response signal compensating the second digital signal to generate a back-end input signal.
