Abstract: A device is provided, which includes one or more antennas and a circuit. The circuit is configured to receive a packet from a transmitter device through the antennas, and obtain channel-state information from the received packet. The circuit includes one or more filters to filter out or recognize the received packet that complies with one or more preset conditions. The circuit uses the channel-state information of the received packet, which complies with the one or more preset conditions, to estimate a status of a channel between the transmitter device and the device.

Abstract: A communication system is provided. The communication system includes an antenna, a power amplifier, a detector and a signal-processing module. The power amplifier provides an output signal to the antenna according to an input signal. The detector provides power information and voltage information according to the output signal. The signal-processing module obtains a loading variation according to the power information and the voltage information, and provides the input signal according to the loading variation. When the loading variation exceeds a threshold value, the signal-processing module performs a digital pre-distortion calibration for the input signal.
