    • An apparatus and a method stabilize a charging current when recharging a battery in a device that uses a rechargeable battery. The device includes a charge module and a controller. The charge module provides a charging current to the battery, and operates in at least one of a Constant Current (CC) mode that maintains the charging current at a fixed value while the battery is charged, and a Constant Voltage (CV) mode that maintains a battery voltage at a reference value. The controller controls the charge module to operate in the CC mode when starting charging, controls the charge module to operate in the CV mode when the battery voltage reaches the reference value, and controls the charge module to operate in the CC mode for at least one time duration after the battery voltage reaches the reference value.

    • A space domain filter detecting method in a multi-antennas wireless communication system, which processes time and space domain interference differently. The space domain filter detecting method comprises the following steps: firstly, the received signals are matched-combined in time domain and space domain; secondly, using the combined signals as an observation value, the space domain filtering is performed; thirdly, an estimated value is subtracted from the filtered signals, and the result is taken as a detection output, which is sent to a determiner in a non-error control coding system to get a hard determination output or is sent to a determiner in an error control coding system to get a soft determination output that is finally sent to a coder. The method promotes the transmission rate and the anti-interference ability and advances the spectrum efficiency.
