Summary:
Terrestrial broadcasting will be shifted from analogue broadcasting to digital broadcasting in Japan. After the digitization, a part of frequency spectrum used for analogue broadcasting in present will be utilized for intelligent transportation system (ITS) and mobile communications [1]. Since the radiation power in ITS is considerably small compared with that of broadcasting or mobile communications, it is worried that the ITS may suffer interference from broadcasting system or mobile communication system when the ITS terminal is close to the broadcasting station or handy terminal of mobile communication system. In this paper, a novel adaptive array is proposed to avoid interferences from such a broadcasting system or mobile communication system. The proposed adaptive array is composed of a power inversion adaptive array (PIAA) [2]-[4] and band pass filters (BPF). In Sec.2, the interference problem for the ITS is explained in detail. The configuration and point of new scheme of proposed system is provided in Sec.3. The effectiveness of the proposed system is evaluated through computer simulations in Sec.4.
