Patent number: 8036621Abstract: There is provided a receiving apparatus having a simple configuration and an excellent ability to eliminate multipath noise, in which an antenna in a good reception state can be instantly selected. A reception signal from an antenna is inputted to an intermediate-frequency amplifying circuit via an antenna switching circuit, a front end and an A/D converting circuit, and an S meter signal from an S meter circuit is inputted to a controlling section via a noise detecting filter and an absolute value circuit. Then, the controlling section compares noise components outputted from the absolute value circuit (noise level) with a threshold value Vth outputted from a threshold value setting section. When the noise level becomes higher than the threshold value Vth, an antenna selection controlling signal is outputted to the antenna switching circuit, and antennas are switched.Type: GrantFiled: April 4, 2006Date of Patent: October 11, 2011Assignee: Fujitsu Ten LimitedInventor: Kiyotaka Nakagawa

Publication number: 20090295636Abstract: An object of the invention is to provide a receiving apparatus in which multipath noise can be reduced. In a diversity receiving apparatus (20), a delay amount of phase shifters (24a, 24b) is changed to reduce a multipath level (Mdc) detected by a multipath detecting unit (33). The multipath detecting unit (33), signal processing parts (23a, 23b), and a combiner (25) are provided to obtain a received signal based on received outputs of a plurality of antennas (21a, 21b) when receiving a radio wave signal modulated by a modulating method, such as an FM, in which no change in amplitude is produced. Therefore, the radio wave signal can be received in a better condition than when received using a single antenna. The multipath detecting unit (33) detects a change in amplitude of the received signal as the multipath level (Mdc).Type: ApplicationFiled: March 31, 2006Publication date: December 3, 2009Applicant: FUJITSU TEN LIMITEDInventors: Isao Taniguchi, Kiyotaka Nakagawa, Kazuo Takayama
