Patent ID: 7830997

Claim:
A diversity receiving device that selects at least one of a plurality of received signals, the diversity receiving device comprising: a plurality of receiving units, each of which is configured to convert one of the plurality of received signals into a baseband signal; a demodulating unit configured to demodulate the baseband signal into a demodulated signal; a clock generating unit configured to generate a clock signal; and a control unit configured to control the clock generating unit, wherein: the control unit selects the at least one of plurality of received signals, the control unit controls the clock generating unit to interrupt clock generation to one of the plurality of receiving units, which converts one of the plurality of received signals other than the at least one of the plurality of received signals, and the diversity receiving device further comprises a synthesizing unit configured to synthesize the demodulated signal and outputs a synthesized demodulation signal, wherein the control unit controls the synthesizing unit to output either selection synthesis diversity or addition synthesis diversity according to intensity of the at least one of the plurality of received signals.
