1. A communication device comprising:
an antenna;
a transmission processor configured to output a second transmission input signal having the same average power as average power of a first transmission input signal and a second amplitude that is greater than a first amplitude of the first transmission input signal;
a radio frequency (RF) chain configured to output an RF output signal to be transmitted through the antenna based on a transmission input signal provided from the transmission processor, and to output a reception input signal based on a signal received through the antenna; and
a reception processor 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.
