WIRELESS BASE STATION, TRANSMISSION METHOD, AND PROGRAM
The present invention is applied to a base station for periodically transmitting a transmission signal to a terminal. The base station includes: a transmitter/receiver that receives a reception signal; a noise verifier that outputs information regarding a generation time and a generation period of the noise that is periodically generated if the reception signal includes the noise; and a transmission timing determiner that determines setting a transmission period of the transmission signal to the same period as the generation period of the noise based on the information regarding the generation time and the generation period of the noise that is output from the noise verifier and shifting a start position of the transmission period by a predetermined time from an arbitrary generation time of the noise, wherein the transmitter/receiver transmits the transmission signal to the terminal at transmission timing of the transmission signal determined by the transmission timing determiner.
