A device and a method for saving power in a mobile electronic device are provided. A mobile electronic device includes a plurality of antennas and a transceiver, wherein the transceiver includes a control unit configured to switch to a low power mode to operate in the low power mode, or to operate at least one of the plurality of antennas in the low power mode when a data non-transmission period occurs for a predetermined time in an active state.

Mobile device for power reduction and method thereof

Synchronization circuits are provided for orthogonal frequency division multiplexing (OFDM) receivers. The synchronization circuits include a fast Fourier transform (FFT) processor and a synchronization unit. The FFT processor is configured to perform FFT of an input signal. The synchronization unit is configured to obtain a channel impulse response (CIR) using an output signal of the FFT processor and relocate an FFT window based on the CIR. Related receivers, methods and computer program products are also provided.
