| 20100246724 | APPARATUS AND METHOD FOR RECEIVING A RADIO SIGNAL - [Problem] The present invention relates to a radio frequency signal receiver, and more particularly, to a radio frequency signal receiver of a communication system, in which local devices exchange a radio frequency signal with each other. The object of the present invention is to provide a radio frequency signal receiver that exactly restores data from a received signal without a complex circuit restoring a phase of a received signal. It is another object of the present invention to provide a radio frequency signal receiver that eliminates noise when the noise is included in the received signal, estimates an exact data rate of the received signal, and exactly restores received information based on the estimated data rate thereof. | 09-30-2010 |
| 20090124221 | DUAL BAND RECEIVER - There is provided a dual band receiver receiving frequency signals in different bands, the receiver including: a first down converter converting a first band signal into a first intermediate frequency signal; a second down converter converting a second band signal into a second intermediate frequency signal; a first voltage control oscillator supplying a first oscillation frequency to the first down converter; a second voltage control oscillator supplying a second oscillation frequency to the second down converter; a first filter passing the first intermediate frequency signal within a desired bandwidth; a second filter passing the second intermediate frequency signal within a desired bandwidth; and a clock generator converting the first oscillation frequency of the first voltage control oscillator into sampling frequencies corresponding to integer multiples of first and second oscillation frequencies and supplying the sampling frequencies to first and second AD converters, respectively. | 05-14-2009 |
