Method for controlling a modulation index of a near field communication device with aid of dynamic calibration, and associated apparatus |
| 摘要 |
A method for controlling a modulation index of a near field communication (NFC) device includes: in a calibration mode of the NFC device, coupling a receiver of the NFC device to a transmitter of the NFC device to form a probing path between the receiver and the transmitter; and in the calibration mode of the NFC device, adjusting at least one portion of a plurality of modulation parameters corresponding to the modulation index according to probed results of outputs of the transmitter, in order to calibrate the modulation index, for use of transmitting through the transmitter in a normal mode of the NFC device. An associated apparatus is also provided. |
