    Abstract: A method, an apparatus, and a transceiver for cancelling multi-carrier transmission interference are provided. The method includes: collecting a high order intermodulation signal in radio frequency signals output by a transmitter; processing the high order intermodulation signal so as to generate a first digital signal; establishing a high order intermodulation model by using the first digital signal and a first baseband signal output by the transmitter; generating a second digital signal by using a coefficient of the high order intermodulation model and a second baseband signal output by the transmitter; and counteracting interference in a digital signal output by a receiver with the second digital signal. By using the embodiments of the embodiments of the invention, high order intermodulation interference of a multi-carrier transmitter on a receiver can be effectively canceled, and therefore, difficulty in duplexer design and requirements on a suppression degree are reduced.

    Abstract: An antenna system with a beam with an adjustable tilt, including: a transceiver (TRX) array module, an antenna element array module, a feeding network module and a Butler matrix module, is provided. The TRX array module includes multiple active TRX submodules and is configured to generate transmission signals that have undergone digital beam forming. The antenna element array module includes multiple antenna elements and is configured to transmit the transmission signals. The feeding network module is configured to form a vertical beam characteristic of the antenna element array module before the antenna element array module transmits the transmission signals. The Butler matrix module is configured to form a horizontal beam characteristic of the antenna element array module before the antenna element array module transmits the transmission signals. The antenna system reduces the feeder loss, reduces the labor and equipment costs, and enables the vertical and horizontal beam characteristics of the antenna to be adjusted more conveniently.

    Abstract: 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.
