Patent ID: 8064370

Claim:
A transmitter performing wireless communication with a receiver having a function of suppressing an interference signal included in a received signal to acquire a desired signal by receiving the interference signal in advance for a predetermined period, the transmitter comprising: a detection unit operable to detect an arriving interference signal; a transmission unit operable to transmit a packet to the receiver; a transmission timing control unit operable to cause the transmission unit to transmit the packet after an elapse of the predetermined period since the detection unit has detected the arriving interference signal, regardless of whether the interference signal is still arriving, such that, when the interference signal is still arriving, the transmission unit will start transmitting the packet after the elapse of the predetermined period since the detection unit has detected the arriving interference signal; and a transmission packet length control unit operable to cause the transmission unit to divide the packet into subpackets during the transmission of the packet and temporarily suspend the transmission of the packet, based on a variation in a level of the arriving interference signal detected by the detection unit during the transmission of the packet, wherein, when the transmission unit transmits the packet at a time and when a new interference signal is expected to arrive before the transmission of the packet has completed, the transmission packet length control unit causes the transmission unit to divide the packet into the subpackets.
