RADIO COMMUNICATION DEVICE AND RADIO COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a radio communication device capable of reducing a calculation load by the reduction of the number of ADCs and DACs for use for communication.

SOLUTION: The radio communication device includes: a plurality of antennas; a plurality of digital-to-analog converters and analog-to-digital converters enabling the switching of operation and suspension; an ADC/DAC control circuit for determining the operation and the suspension of each digital-to-analog converter and each analog-to-digital converter; a circuit for transmitting an analog signal generated by the digital-to-analog converter by converting it into a frequency of a radio section, and for receiving a signal in a radio section to frequency convert and output to the analog-to-digital converter; a circuit for demodulating a received data from a digital signal generated by the analog-to-digital converter; and a circuit for generating a digital signal for transmission to output to the digital-to-analog converter. The ADC/DAC control circuit determines the number of analog-to-digital converters or digital-to-analog converters to be operated, based on the communication state of the radio communication device, to control the operation thereof.
