ABSTRACT:
A radio communication apparatus of the present invention comprises a radio unit capable of transmitting or receiving a first radio communication signal of a Bluetooth standard and a second radio communication signal of a cordless phone standard and a synchronism discriminator for discriminating a radio communication standard signal. The radio communication apparatus switches between first and second radio communication modes in response to a discrimination result of the synchronism discriminator, detects a type and a weight of a sound error every mode, and adds or subtracts the weight of the sound error in a present slot to or from a weight of a sound error in the previous slot in response to a degree of the sound error in the present slot. This structure allows a single apparatus to transmit or receive both of two kinds of radio communication standard signals, and the sound error is adequately and precisely handled in response to the type and weight of the sound error, thereby improving quality of the sound signal.
