A communicating apparatus comprising a receiving module which comprises: a first receiving line, for receiving a second input data stream; a timing detecting apparatus, for detecting timings for a plurality of data units of the second input data stream; a data allocating apparatus, for allocating the second input data stream to X allocated data streams, wherein the X is a positive integer and the X is larger or equals to 2; and X second receiving lines, for respectively transmitting one of the X allocated data streams.

Communicating apparatus

An echo signal processing apparatus is disclosed. The echo signal processing apparatus is utilized for generating a cancellation signal by using group phenomenon of a frequency response of an echo signal to remove the echo signal. The echo signal processing apparatus has lower cost and is able to remove the echo efficiently.

Apparatus for processing echo signal and method thereof

A communication apparatus with echo cancellation includes a transmitter, a receiver, a digital echo cancellation circuit, a parameter control circuit, and an analog echo cancellation circuit. The digital echo cancellation circuit determines an echo estimation component according to a digital output signal, and performs a digital echo cancellation on a digital input signal according to the echo estimation component. The parameter control circuit generates a control signal according to the echo estimation component. The analog echo cancellation circuit includes a first echo cancellation resistor and a second echo cancellation resistor, wherein the resistances of the first echo cancellation resistor and the second echo cancellation resistor are adjusted according to the control signal.
