摘要： There are provided a radio system and a radio communication device capable of removing a phase noise superimposed on a reception signal and a phase noise generated in the system of a reception radio unit. In this system, a radio transmission device (101) transmits a multiplex signal multiplexed so that a pilot signal is placed on the center frequency. A radio reception device (151) frequency-multiplies a reception signal by a pilot signal having the same frequency error and phase noise as the reception signal, and frequency-multiplies the phase noise contained in a local oscillation signal used when subjecting the reception signal to frequency conversion, by using the signal having the same phase noise. Thus, it is possible to remove the frequency error and phase noise contained in the reception signal and the phase noise in the reception system.

摘要： An array antenna reception apparatus capable of calibrating a received signal with high accuracy without generating unnecessary radiations at an antenna section even when the power level of the received signal is low. In this apparatus, reference signal generation section (123) operates only when the power level of the received signal captured by antenna section (111) is low and a reference signal is generated. Error calculation section (122) compares information (S3) on the received signal multiplexed with the reference signal with calibration signal (S4) to thereby calculate an error of the received signal produced in the received signal due to signal processing at reception unit (110) and instructs received signal processing section (121) to compensate for the received signal based on the calculated error of the received signal.
