一种使用多个通信技术以供同时通信的系统被揭示。该系统包括回送接收器、接收器、及噪声移除器组件。该回送接收器被配置成获得已耦合信号及从该已耦合信号产生噪声信号。该噪声信号包括直接发送噪声。该接收器被配置成接收链接收信号及提供来自该链接收信号的接收信号。该噪声移除器组件被配置成从该噪声信号及该接收信号产生想要接收信号。

A system using multiple communication technologies for concurrent communication is disclosed. The system includes a loopback receiver, a receiver, and a noise remover component. The loopback receiver is configured to obtain a coupled signal and generate a noise signal from the coupled signal. The noise signal includes direct transmission noise. The receiver is configured to receive a chain receive signal and to provide a receive signal therefrom. The noise remover component is configured to generate a wanted receive signal from the noise signal and the receive signal.
