A method for automatic frequency control, as well as transmit - / receiving device

摘要

The present invention provides a method for automatic frequency control of ready. A transmission frequency - compensation value, from a first frequency shift - value and a second frequency shift - value in correspondence to an environmental condition of selected. The transmission frequency for the transmission of signals, in correspondence with the transmission frequency - compensation value is compensated for.According to the invention, to compensate for the transmission frequency of the transmission frequency - compensation value to a difference between a received frequency and the transmission frequency is added in order to obtain a frequency signal, and, a feedback signal of the transmission frequency to the frequency signal is added in order to obtain the transmission frequency.
