無線中継装置
Document Type and Number:
Japanese Patent JP3588430
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a wireless repeater that can quickly eliminate the effect of a reflected wave and a sneak path wave. SOLUTION: An interference canceller 16 has a reflecting wave canceller function that eliminates a reflecting wave component included in a received signal and a sneak path wave canceller function that eliminates a sneak path wave component included in the received signal. A control section 24 can control power of a transmission signal retransmitted from a transmission antenna 22 and limits the power of the transmission signal to start elimination of the reflected wave by the reflecting wave canceller function of the interference canceller 16. After a lapse of a prescribed time, the control section 24 recovers the power of the transmission signal again and starts elimination of the sneak path wave with the sneak path wave canceller function of the interference canceller 16.
