Abstract: The present disclosure provides a communication device and an operating method. The communication device includes an antenna, a transmission processor, a radio frequency chain, and a reception processor. The transmission processor is configured to output a second transmission input signal with the same average power as the average power of a first transmission input signal and a second amplitude greater than a first amplitude of the first transmission input signal. The RF chain is configured to output an RF output signal to be transmitted through the antenna, based on a transmission input signal, and to output a reception input signal based on a signal received through the antenna. The reception processor is configured to check an out-of-band blocker by detecting a peaked frequency spectrum based on the reception input signal and to adjust a reception characteristic parameter of the RF chain based on an amplitude of the peaked frequency spectrum.
