Abstract (in Japanese) (See Japanese page) 
(in English) As a counter measure of co-channel interference at digital
broadcast--wave relay station, we have considered an application of
MMSE adaptive array. So far, we suppose that interference incident to
main lobe of receiving antenna with sharp directivity is needed to be
cancelled using signal processing. However, it becomes clear in a
practical network examination that a demand to cancel co-channel
interference which incident to side lobe of receiving antenna is
exists. This paper proposes an interference cancellation system for
ISDB\,-T using an auxiliary antenna. In this system, a main and
auxiliary antenna are directed to desired and interference waves
respectively, and interference component in a signal received by main
antenna is cancelled with a replica of the interference generated from
a signal received by auxiliary antenna, utilizing a difference of
there interference D/U. Numerical examples and in-laboratory
experimental results are presented to show the effectiveness of a
proposed method.
