Abstract
Embodiments of the present disclosure provide a signal transmitting method. According to the method, in a signal transmitting process, before entering a digital to analog converter (DAC), a first frequency modulated signal of a high-pass channel is first subjected to nonlinear compensation and gain mismatch compensation. In the process, a nonlinear compensation coefficient and a gain mismatch compensation coefficient are determined according to an output voltage of the high-pass channel and an output frequency of a voltage-controlled oscillator (VCO) during a calibration stage.
