Abstract: Disclosed are a calibration method and a calibration circuit. The calibration method and the calibration circuit effectively calibrate the mismatches between the first signal path and the second signal path of a transmitter by calibrating a plurality of tap coefficients of the FIR filter configured in the second signal path and optimizing the tap coefficients. The calibration and optimization for the tap coefficients of the FIR filter is according to differences between the electrical characteristics the DAC convertor and the LPF in the first signal path and differences between the DAC convertor and the LPF in the second signal path. These differences are obtained when the data transmission has not yet started by the transmitter (that is, when the transmitter is working in a training mode).

Abstract: A WLAN player for synchronizing playing speed includes a speed adjusting module, which is adapted to adjust a speed that the WLAN player plays a medium according to a first playing-progress value and a first clock value of another WLAN player, so as to synchronously play the medium together with said another WLAN player.

In this way, a synchronization error between the WLAN players is effectively decreased.

Abstract: Disclosed are a calibration method and a calibration circuit. The calibration method and the calibration circuit effectively calibrate the mismatches between the first signal path and the second signal path of a receiver by calibrating a plurality of tap coefficients of a finite impulse response filter configured in the second signal path and optimizing the tap coefficients. The calibration and optimization for the tap coefficients of the finite impulse response filter is according to differences between the electrical characteristics the analog-to-digital convertor and the LPF in the first signal path and differences between the analog-to-digital convertor and the LPF in the second signal path. These differences are obtained when the data reception has not yet started by the receiver (that is, when the receiver is working in a training mode).
