The invention provides a method and a communication device for cancelling
echoes in the communication device, comprising:
receiving path means and sending path means for receiving and sending
respective signals, and
echo compensating means for generating an echo control signal which is
representative of a perceived echo, which echo compensating means are
coupled between the sending and the receiving path means, and comprise an
echo digital control signal generating means, and a digital-to-analog
convertor coupled to the digital control signal generating means and to
the receiving path means. Hardware and software implementation are easy
and the dynamic range of an analog-to-digital convertor present in the
receiving path is limited.
