Method for cancelling echoes in a communication system, a communication device, and a radio base station of a cordless telephone device

摘要

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, andecho 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.
