摘要： The present invention provides a wireless communication device and a wireless communication system which can improve the error detection accuracy with the sound quality maintained to some extent even if the communication environment is deteriorated. A cordless phone establishes a digital link on a wireless channel between a master device and a slave device, compresses a sound signal in an ADPCM scheme, and carries the sound signal in a sound packet to perform communication. In a master device side, a PCM signal is converted into ADPCM data by an ADPCM encoding unit. Next, the least significant bit of n-bits is set according to the number of “1” of the n-bits of the ADPCM data by a transmission conversion table. In a slave device side, it is determined whether an error has occurred according to the number of “1” of the n-bit data in received data. If the error exists, the n-bit sound data is converted into mute data through a reception conversion table. The sound data converted through the reception conversion table is converted into a PCM signal from an ADPCM format by an ADPCM decoding unit.

摘要： A base unit of a radio communication apparatus of the present invention includes a controller that discriminates whether or not company identifying information transmitted from a cordless handset is specific information in connecting a line in a Bluetooth (BT) communication mode, performs communication in another radio communication standard (company's own mode) on determining that the company identifying information is the specific information, and performs the communication in a BT standard on determining that the company identifying information is not the specific information, and a registering unit for registering an ID peculiar to the apparatus. This simple structure allows long-distance communication at higher sound quality with the other apparatus capable of performing CDL communication in the company's own mode using an error handling function, and sound communication at usual sound quality in a BT data format allowing short-distance communication even when the company identifying information is not the specific information.

摘要： 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.
