Title:
TIME-DIVISION DUPLEX COMMUNICATION DEVICE AND METHOD FOR PREVENTING INTERFERENCE TO RECEPTION BY THE SAME
Document Type and Number:
WIPO Patent Application WO/2011/030512
Kind Code:
A1
Abstract:
Disclosed is a time-division duplex communication device capable of distinguishing between interrupts caused by interference received during the reception time, interrupts occurring upon the completion of measurement of received signal strength, and interrupts caused by power leaking to the reception system during the transmission time. The time-division duplex communication device is provided with a variable attenuator (7) for adjusting the power of a received signal; an interrupt cause detection unit (11) for detecting an interrupt signal on the basis of the received signal; a reception timing determining unit (21) for determining whether the interrupt signal had been caused by received interference; and an interference determining unit (31) for controlling the variable attenuator (7) when it has been determined that the interrupt signal had been caused by received interference.
