    • The invention provides a full-duplex communication device. The full-duplex communication device comprises a first adaptive filter, a second adaptive filter, a channel decoupling module, and a frequency processing module. The first adaptive filter having a first tap length filters out echoes of a far-end talker from a first near-end signal carrying voices of a near end talker according to a far-end signal carrying voices of the far-end talker to obtain a second near-end signal. The second adaptive filter having a second tap length less than the first tap length filters out echoes of the far-end talker from the first near-end signal according to the far-end signal to obtain a third near-end signal. The channel decoupling module generates a fourth near-end signal and subtracts the second near-end signal from the third near-end signal to obtain a fifth near-end signal. Finally, the frequency processing module obtains a six near-end signal.
    • 本发明提供一种全双工通信设备。 全双工通信设备包括第一自适应滤波器,第二自适应滤波器,信道解耦模块和频率处理模块。 具有第一抽头长度的第一自适应滤波器根据携带远端讲话者的语音的远端信号,从携带近端讲话者的语音的第一近端信号中滤除远端讲话者的回波,以获得 第二近端信号。 具有小于第一抽头长度的第二抽头长度的第二自适应滤波器根据远端信号从第一近端信号滤除远端讲话者的回波,以获得第三近端信号。 信道解耦模块产生第四近端信号,并从第三近端信号中减去第二近端信号,以获得第五近端信号。 最后,频率处理模块获得六个近端信号。

    • A broadside small array microphone beamforming apparatus comprises first and second omni-directional microphones, a microphone calibration unit, and a directional microphone forming unit. The first and second omni-directional microphones respectively convert voice from a desired near-end talker into first and second signals. The second and first omni-directional microphones and the desired near-end talker are respectively arranged at three points of a triangle. The microphone calibration unit receives the first and second signals and correspondingly outputs first and second calibration signals. The directional microphone forming unit receives the first and second calibration signals to generate a first directional microphone signal with a bidirectional polar pattern. The adaptive channel decoupling unit receives the first calibration signal and the first directional microphone signal to generate a first main channel signal and a first reference channel signal for noise detection.
