Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 12:
13. A communication device comprising:
an antenna;
a modem configured to output a transmission input signal and to process a reception input signal; and
a radio frequency (RF) chain configured to output an RF output signal that is to be transmitted through the antenna, based on the transmission input signal and to output a reception input signal based on a signal received through the antenna, wherein
the modem is configured to calculate a signal to noise ratio (SNR) based on the reception input signal,
to change a first transmission input signal to a second transmission input signal based on whether the SNR is less than a reference SNR, and
to detect 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.
