Document Type and Number:
WIPO Patent Application WO/2020/184041
Kind Code:
A1
Abstract:
[Problem] To suppress noise generated in FM demodulation during transmission according to a TDMA system. [Solution] This FM communication device is provided with an FM demodulation unit 32, a TDMA transmission detection unit 34F, and an output sound control unit 35. The FM demodulation unit 32 demodulates an FM communication signal received by an antenna capable of receiving a TDMA signal and an FM communication signal that have overlapping frequency bands. The TDMA transmission detection unit 34F detects that a TDMA signal is being transmitted. The output sound control unit 35 controls an output sound from the FM demodulation unit 32 during the transmission of the TDMA signal, using the detection result from the TDMA transmission detection unit 34F.
