ABSTRACT:
In a combining diversity apparatus for a digital multi-valued modulation RF signal, at least first and second receiving antenna units having a space diversity relationship, first and second frequency conversion units for converting the RF signal into first and second IF signals, a combining unit for phasing-combining the first IF signal with the second IF signal, and determination units for determining whether or not the first and second IF signals are interference signals, are provided. When the first or second IF signal is an interference signal, the first or second IF signal is shut off or attenuated by a first switching unit or a second switching unit.
