  • Communication apparatus, distributed antenna system, and switching method
    Patent number: 10644741
    Abstract: According to an embodiment, a communication apparatus includes a switching unit, a reception unit, a rising edge detector, a symbol detector, and a switching timing detector. The switching unit switches a transmission operation of a signal in the communication apparatus between uplink signal transmission and downlink signal transmission. The reception unit receives a signal transmitted in a time division multiplexing scheme. The rising edge detector detects a rising edge of a received signal received by the reception unit. The symbol detector detects a symbol of a signal indicating a guard time in the time division multiplexing scheme from the received signal. The switching timing detector detects a switching timing of the transmission operation from the switching unit on the basis of detection results of the rising edge detector and the symbol detector.
