Abstract
The diversity reception device includes an antenna switching unit configured to select and switch to a determined chain number of antennas out of a plurality of antennas; and an antenna interchange control unit configured to control the antenna switching unit to interchange an antenna. The antenna interchange control unit compares a carrier-to-noise ratio measured by a demodulation circuit of a demodulation unit of each chain, controls the antenna switching unit to sequentially switch connection with an antenna of a chain having a lowest carrier-to-noise ratio to connection with antennas connectable to the chain, and interchanges the antenna of the chain having a lowest carrier-to-noise ratio with an antenna estimated to have a highest carrier-to-noise ratio on the basis of the input level measured by the level detection unit or an antenna having a highest input level measured by the level detection unit among the connection-switched antennas.
