1. An encoder-integrated transmitter comprising:
an encoder-integrated modulation unit including one field programmable gate array (FPGA) to control a measurement circuit, configured to collect measurement data from the measurement circuit to configure transmission frame data, and modulate the transmission frame data into a digital modulation signal; and
an amplifier configured to convert the digital modulation signal into a passband analog radio frequency (RF) signal and then amplify the passband analog RF signal to a high power,
wherein the encoder-integrated modulation unit includes:
a look-up table-based frequency pulse filter configured to calculate an argument according to a stream of the transmission frame data input from the encoder unit and output an output value corresponding to the argument calculated from a look-up table;
a digital integrator configured to digitally integrate a signal output from the look-up table-based frequency pulse filter; and
a quadrature modulator configured to modulate a signal digitally integrated by the digital integrator into an in-phase component and a quadrature component and output the in-phase component and the quadrature component.
