Abstract

PURPOSE: To conduct the test of a radio communication equipment without providing a different transmission/reception device for test, to miniaturize the equipment and to reduce cost by operating a reception part during time when the reception part originally stops and conducting the test of the radio communication equipment. CONSTITUTION: A radio signal transmitted from a transmission part 1 is emitted from a first transmission/reception antenna 6 or a second transmission/reception antenna 7 through a first switch 4 or a second switch 5. At that time, reception opposite parties are a slave station and a moving station. Since a first reception part 2 and a second reception part 3 are TDD communication systems, they originally stop the operation. The first reception part 2 and the second reception part 3 receive the radio signals from the transmission part 1 at timing similar to a reception opposite station by using time received by the reception opposite station. When it is recognized that a reception signal is more than a prescribed level and it has the same pattern as the radio signal transmitted from the transmission part 1 by pattern matching, it is realized that the transmission part 1, the first reception part 2 and the second reception part 3 normally operate.
