摘要： Embodiments of the present invention disclose a transceiver and an interference cancellation method. The transceiver includes a transceiver digital processing unit, a transmitting path, a receiving path, an injection path, a duplexer, and a cancellation module, where the transceiver digital processing unit is configured to generate a transmitting signal, an injection signal, and a control signal, and obtain a received signal; the injection path is configured to output, to the cancellation module and the duplexer, the injection signal generated by the transceiver digital processing unit; and the cancellation module is configured to perform, according to the control signal, cancellation processing on a signal that is output to the duplexer by the transmitting path and the signal that is output by the injection path to obtain a cancellation signal, and input the cancellation signal to the receiving path. By using the present invention, interference cancellation can be adaptively implemented by using the cancellation module, thereby implementing miniaturization of a base station device under a condition of decreased interference.

摘要： Embodiments of the present invention disclose an antenna device and system. The antenna device includes: an antenna array, configured to radiate or receive an electromagnetic wave signal; a feed network, configured to connect the antenna array and a signal multiplexer; at least one signal multiplexer, where each signal multiplexer, including one combiner port and at least two divider ports, is configured to divide one path of signal from the feed network into at least two paths of signal, or combine at least two paths of signal to one path of signal and transmit the one path of signal to the feed network; and at least two interface modules, where each of the interface modules, connected to a passive module or an active module, is configured to receive a signal sent from the passive module or the active module, or send a signal to the passive module or the active module. The present invention can be used as an active antenna system, and may also be used as a passive antenna, for sharing the antenna array and other parts in the active and passive antenna systems.

摘要： The present invention provides a communications device and a method for monitoring its performance. The communications device includes a communications processing unit, configured to perform a function of the communications device; a collection unit, configured to collect a signal output by the communications processing unit; and a monitoring unit, configured to monitor the signal collected by the collection unit to locate a fault. In embodiments of the present invention, fault monitoring of the communications device can be implemented by itself, thereby avoiding a problem caused by an external dedicated monitoring device.

摘要： An interference cancellation method and apparatus and also a filter are disclosed to cancel the interfering signals leaked to the receiving channel, and enable the receiving channel to suppress the transmitted signal. The method includes: dividing a transmitted signal into a first transmitted signal and a second transmitted signal, and then inputting the first transmitted signal into a first transmitting filter and inputting the second transmitted signal into a second transmitting filter symmetric to the first transmitting filter; adjusting the first interfering signal and the second interfering signal to make opposite phases of the signals; and combining the signals of opposite phases. The method provided herein can cancel the interfering signals leaked to the receiving channel, the receiving channel suppresses the transmitted signal effectively, and the interference caused by the transmitted signal onto the received signal is cancelled.
