A sorting method of communication data is executed by a communication apparatus including a processor. The processor sorts communication data packages according to sorting indexes by a first sorting procedure to establish a first sorting list, and determines at least one priority data package and general data packages. The processor sorts the general data packages according to the sorting indexes by a second sorting procedure to establish a second sorting list, and decodes the priority data package. After the priority data package is decoded, the processor determines whether a remaining time period of a time slot is less than an invalid time period of the time slot. If not, the processor executes a worst case. Since the processor decodes the communication data packages that have been sorted, the remaining time period of the time slot can be effectively utilized to improve an efficiency of the communication apparatus.

Sorting method of communication data and communication apparatus thereof

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

A receiver having Inphase-Quadrature (I-Q) imbalance compensation and an I-Q imbalance compensation method are provided. The receiver calculates a cross-ratio parameter according to a first ideal receiving value and a first ideal conjugate receiving mirror of a first receiving signal and a second ideal receiving value and a second ideal conjugate receiving mirror of a second receiving signal. The receiver calculates an I-Q imbalance compensation parameter according to the cross-ratio parameter, the first ideal receiving value, the first ideal conjugate receiving mirror, the second ideal receiving value, the second ideal conjugate receiving mirror, the first receiving signal and the second receiving signal. The receiver compensates a third receiving signal according to the I-Q imbalance compensation parameter.

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