摘要： The disclosure provides a receiver and an automatic offset cancellation (AOC) method thereof. The receiver includes a receiving channel circuit and an AOC circuit. The receiving channel circuit generates an equalized differential signal including an equalized first-end signal and an equalized second-end signal according to an input differential signal. The AOC circuit detects a peak of the equalized first-end signal to generate a first peak detection result. The AOC circuit detects a peak of the equalized second-end signal to generate a second peak detection result. The AOC circuit compares the first peak detection result with the second peak detection result to generate a comparison result. The AOC circuit compensates a mismatch of an input differential pair in the receiving channel circuit according to the comparison result.

摘要： In a noise canceler, interference signals received by sub-antennas 12 are cross-correlated by a first correlation-value calculation unit and the peaks of the interference signals are detected by a first peak detector. Interference signal information is acquired by a first-interference-signal information acquisition unit and the interference signals are synthesized by an interference signal synthesizer. A signal received by a main antenna and the synthesized interference signal are correlated by a second correlation-value calculation unit and the peak of the synthesized interference signal is detected by a second peak detector. The interference signal information is acquired by a second interference-signal-information acquisition unit and an interference signal replica is generated by an interference signal replica generator. The interference signal replica is subtracted by an interference signal removal unit from the signal received by the main antenna.

摘要： The disclosure provides for interference mitigation for wireless signals in unlicensed spectrum. A wireless device may receive a combined signal including a first radio access technology (RAT) signal and a second RAT signal. The wireless device may generate, using a first RAT receiver in a first processing path, a channel estimate for the first RAT signal based on a previously decoded signal of the first RAT. The wireless device may reduce interference to the second RAT signal caused by the first RAT signal, in a second processing path, using the channel estimate. The wireless device may further decode the second RAT signal. The wireless device may remodulate the decoded signal using a transmitter to generate a remodulated second RAT signal. The remodulated second RAT signal may be canceled from the combined signal. The wireless device may decode a remaining portion of the combined signal including the first RAT signal.

摘要： A method of interference cancellation is proposed. A UE obtains configuration information of a data transmission from a neighboring cell via an interference channel in a mobile communication network. The UE receives radio signals on a set of data resource elements as determined based on the obtained configuration information. The UE then estimates the interference channel corresponding to the data transmission from the neighboring cell based on the received radio signals on the set of data resource elements. Finally, the UE cancels the data transmission from the neighboring cell based on the estimated interference channel.
