A wireless communication device and a digital self-interference estimation method thereof are provided. The wireless communication device, at respective timings, receives a plurality of self-interference signals and generates a plurality of ideal transmitting signals. The wireless communication device calculates a signal adjusting vector based on the self-interference signals and the ideal transmitting signals at different timings. The wireless communication device generates a main ideal transmitting signal at a main timing, and calculates, based on the signal adjusting vector, a main self-interference signal corresponding to the main timing according to the received self-interference and the main ideal transmitting signal.

Wireless communication device and digital self-interference estimation method thereof

A receiver with Inphase-Quadrature (I-Q) imbalance compensation and an I-Q imbalance compensation method thereof are provided. The receiver chooses a first receiving signal which includes a first data and a first noise, as well as a second receiving signal which includes a second data and a second noise from a plurality of receiving signals. The first data have a first positive frequency data and a first negative frequency data, while the second data have a second positive frequency data and a second negative frequency data. The receiver calculates an I-Q imbalance compensation parameter according to the first receiving signal and the second receiving signal, and compensates for a third receiving signal according to the I-Q imbalance compensation parameter. The I-Q imbalance compensation method is applied to the receiver to implement the aforesaid operations.

Receiver with inphase-quadrature imbalance compensation and inphase-quadrature imbalance compensation method thereof
