ABSTRACT:
A receiver has a plurality of receiving systems connected to a plurality of antennas, respectively, and a selective switching circuit for carrying out selective switching between output signals from the plurality of receiving systems to output an output signal from a receiving system in the most satisfactory receiving state, wherein the selective switching circuit has a fuzzy inference operation unit for discriminating receiving states of respective receiving states by a fuzzy inference. Accordingly, it is possible to synthetically judge the receiving state of the receiver to easily and stably select the optimum receiving system in the receiver.
