Mobile communication terminal device |
摘要 |
A mobile communication terminal device of the present invention includes: a voltage detector for detecting a battery voltage at the time of a voltage drop; a correction phase storage section for storing pieces of correction phase information each having a characteristic opposite to that of a phase error in a carrier wave produced due to a drop in the battery voltage; a correction phase outputting section for selecting correction phase information based on the battery voltage at the time of the voltage drop and outputting the selected correction phase information to a baseband modulator to change phase information in a baseband signal; and a modulator for modulating a carrier wave according to the baseband signal output from the correction phase outputting section so as to cancel the phase error included in the carrier wave.
