Abstract
On-air relay has the advantages of low deployment cost and efficient use of frequency to expand DTTB (Digital Terrestrial Television Broadcasting) throughout Japan. However, there are severe problems of CCI (Co-Channel Interference) caused by interference from other transmitting stations. We have been developing a co-channel interference canceller utilizing an adaptive array antenna to remove such interferences. In this paper, we show the results of a long term field trial for an on-air relay using a trial co-channel interference canceller where the difference in angle of arrival between the desired wave and a CCI wave is 3 degrees.
