Abstract:
1. A wireless communication device, which includes a base unit and a handset, establishes a digital link on a wireless channel between the base unit and the handset, and performs communication by a sound packet that includes a plurality of digital sound data and error detection bit data, the error detection bit data including at least one bit, the wireless communication device comprising: a unit that obtains the digital sound data by adaptive differential pulse code modulation (ADPCM), a total number of bits of the respective ADPCM data is fixed, and the error detection bit data being at least one bit except for a plurality of bits input to an adaptive inverse quantizer of the ADPCM, a data transmission unit which converts a part of the digital sound data into the error detection bit data to transmit the data with the error detection bit data; and a data conversion unit which converts the digital sound data according to a value of the error detection bit data received from the data transmission unit.
