Abstract:
A method and an apparatus for tuning an FIR filter in an in-band full duplex transceiver. The method for tuning an FIR filter includes: converting an input signal of the FIR filter into a first signal that is a baseband signal; converting a signal obtained by subtracting an output signal of the FIR filter from the self-transmitted interference signal into a second signal that is the baseband signal; and calculating attenuation of the FIR filter using the first signal and the second signal.
