An object of the invention is to stabilize the convergence operation at the automatic impedance matching time and ensure the reception quality in the convergence process in a fading environment in a radio communication apparatus which performs automatic impedance matching between an antenna and a Radio frequency section to decrease the impedance matching loss, for example, when the apparatus is brought close to a human body. A radio communication apparatus of the invention includes a Radio frequency section 3 which converts a received signal into a baseband signal, a variable impedance unit 2 which adjusts impedance between an antenna 1 and the Radio frequency section 3, a pilot signal extraction unit 4 which extracts a pilot signal from the baseband signal, a first channel compensation unit 5 which performs channel compensation using an output of the pilot signal extraction unit, an impedance control adequacy detection unit 7 which detects impedance control adequacy using an output of the first channel compensation unit, an impedance control unit 8 which controls the variable impedance unit 2 using an output of the impedance control adequacy detection unit, a second channel compensation unit 6 which performs channel compensation using the pilot signal, and a demodulation section 9 which performs the demodulation operation using an output of the second channel compensation unit.
