Zusammenfassung:The present invention discloses a transceiver that implements a frequency domain cancellation of a transmit (Tx)-modulated spur associated with a transceiver. The transceiver comprises a baseband receive (Rx) path configured to propagate a receive signal in frequency domain, associated with an Rx signal path of the transceiver, forming a baseband Rx signal, wherein the baseband Rx signal comprisesa wanted Rx signal and an unwanted transmit (Tx) modulated spur. The transceiver further comprises a baseband Tx path configured to propagate a Tx signal in frequency domain, associated with the Tx signal path of the transceiver, thereby forming a baseband Tx signal. In addition, the transceiver comprises a cancellation circuit coupled to the baseband Rx path, configured to receive the baseband Rx signal and the baseband Tx signal, and generate a cancellation signal based thereon, in order to cancel the unwanted Tx modulated spur from the baseband Rx signal. 公开了一种实现与收发器相关联的发送(Tx)调制杂散的频域消除的收发器。该收发器包括基带接收(Rx)路径,该基带接收(R
