Patent ID: 7373129

Claim:
A radio communication terminal comprising: a receiver connected to a receiving antenna; and an interference canceller for canceling a radiated noise component of electronic equipment from a received signal output from said receiver; wherein said interference canceller includes: a band converting part connected to electronic equipment, for converting said radiated noise from said electronic equipment to the same band as that of the output received signal of said receiver; a radiated noise predictor for generating a pseudo interference signal based on the converted output of said band converting part; and an adder for adding together said received signal and said pseudo interference signal to cancel said radiated noise component in said received signal; and wherein said radiated noise predictor includes: an amplifier connected to the output of said band converting part, for controlling the level of the radiated noise obtained therefrom; a phase shifter connected in series to said amplifier, for controlling the phase of said radiated noise; and a control part for controlling the gain of said amplifier and the phase-shift amount of said phase shifter based on the output from said adder.
