摘要： A base transceiver station for a radio communication system comprises a transmitter unit (TU), a receiver unit (RU) and a transmit path between the transmitter unit (TU) and an antenna. The receiver unit (RU) determines output data from received signals and the transmitter unit (TU) converts input data into transmitted signals and pre-distorts the transmitted signals using at least one compensation value. The base transceiver station comprises also a branching unit for transferring at least a portion of a transmitted signal from the transmit path to the receiver unit (RU) and a processing unit (PU) which is adapted to receive a representation of the input data and the output data. The processing unit (PU) compares the input data to the output data, determines a first compensation value for the pre-distortion according to the comparison and updates the compensation value of the transmitter unit (TU) with the first compensation value. Methods and computer programs embodying the invention are also described.

摘要： A transceiver transmits first and second signals on first and second transmit radio frequencies. After detecting a received signal, intermodulation distortion caused by transmission of the first and second signals is suppressed, reduced, and/or eliminated using information associated with the first and second transmitted signals. More specifically, the information associated with the first and second transmitted signals is used to calculate or otherwise obtain a correction factor that corresponds to the intermodulation distortion. The correction factor is subtracted from the received signal to suppress the intermodulation distortion.
