Title:
DIVERSITY RECEIVER AND DIVERSITY RECEP TION METHOD
Document Type and Number:
WIPO Patent Application WO/2014/087694
Kind Code:
A1
Abstract:
A diversity receiver (1) is provided with receiving circuits (101)and (10N), a diversity combining unit (12), and an oscillation control unit (11). The receiving circuit (101) uses a plurality of lower-side oscillation frequency signals supplied from a first local oscillator to convert the frequency of a received analog signal obtained by a first receiving system to generate a plurality of lower-side low frequency signals and adds the plurality of these lower-side low frequency signals to generate a first addition signal. The receiving circuit (10N) uses a plurality of upper-side oscillation frequency signals supplied from a second local oscillator to convert the frequency of a received analog signal obtained by a second receiving system to generate a plurality of upper-side low frequency signals and adds the plurality of these upper-side low frequency signals to generate a second addition signal. The oscillation control unit (11) controls the lower-side oscillation frequency signals so that the frequency bands of the plurality of lower-side low frequency signals adjoin each other, and controls the upper-side oscillation frequency signals so that the frequency bands of the plurality of upper-side low frequency signals adjoin each other.
