摘要： A wireless device includes a radio-frequency module, a modem module, and a control unit. The radio-frequency module and the modem module operate either in a first operation mode or in a second operation mode. The control unit, coupled to the RF and the modem module, generates a control signal to indicate to the RF and the modem module to operate in the first operation mode or to operate in the second operation mode. A first set of signal formats corresponding to the first operation mode is a superset of a second set of signal formats corresponding to the second operation mode, and a first power consumption corresponding to the first operation mode is higher than a second power consumption corresponding to the second operation mode.

摘要： An adaptive filter is disclosed, having a plurality of computation groups, a plurality of computation circuits, a summation circuit, a slicer circuit, an updating circuit, and a control circuit. Each computation group corresponds to an equalization parameter and has a plurality of memory cells. When the corresponding equalization parameter of a computation group is greater than a predetermined value, the control circuit configures the computation group and the computation circuit to collaboratively generate an output of the computation group. The summation circuit sums up the outputs of the computation groups to produce a filter output. The slicer circuit generates a slicer output according to the filter output. The updating circuit updates the equalization parameters according to the filter output and the slicer output.
