Patent ID: 8824344

Claim:
A time division duplex communication apparatus comprising: an adjustment unit that adjusts a power of a reception signal to a second power below an overflow threshold of an analog to digital converter; an interruption detection unit that detects an interruption signal from the reception signal; a determination unit that determines whether the interruption signal is due to a received interference wave by using a temporal window set to a time slot width dedicated for reception in a plurality of time slots used as a reception timing; a register that stores the determination result by the determination unit; and a control unit that controls the adjustment unit when the determination result determines that the interruption signal is due to the received interference wave is stored in the register, wherein the determination unit determines that the interruption signal is caused by the received interference wave when the interruption signal is detected during a temporal window, wherein the temporal window begins after completion of a measurement of received power and ends before the start of the measurement of received power, and wherein the apparatus does not transmit one or more signals during the temporal window.
