Abstract (in Japanese) (See Japanese page) 
(in English) The ITS communication system which will be available in 2012 exists in 700MHz band between the digital television broadcasting and the next generation telecommunication systems on the frequency domain. Under the assumption that such a frequency allocation would exist, we investigate some interference reduction techniques. To begin with, there is transmission power control (TPC) in IEEE802.11h as a technique to protect the interference for another system. However, since TPC reduces the transmit power, there is concern that communication charasterics might degrade. In this paper, we propose new interference reduction systems which can decrease the degradation of communication charasterics. In particular, we’ve developed simulators to evaluate third order intermodulation distortions and communication charasterics. Results show that new methods can improve communication charasterics.
