DIVERSITY RECEIVER

PROBLEM TO BE SOLVED: To improve efficiency in a circuit scale and costs in a diversity receiver receiving a signal with a plurality of antennas. SOLUTION: The diversity receiver has: a plurality of systems (M) of diversity sections; a composite means 1 for compositing a reception signal processed by each of the plurality of systems of diversity sections; and a demodulation means 2 for demodulating the signal of the composited result by the composite means. Each of the plurality of systems of diversity sections comprises: a plurality of (N) antennas Ai-1 to Ai-N (i=1 to M); a composite change means Bi for compositing or changing a signal received by each of the plurality of antennas; and a frequency conversion means Ci for performing frequency conversion to a composed or changed signal by the composite change means.
