Abstract: PURPOSE: A band-pass sampling reception apparatus, filter design, and re-configuration method are provided to enable a single ADC(Analog Digital Convertor) to accurately receive signals for all frequency bands by effectively eliminating aliasing effects in a baseband. CONSTITUTION: An ADC(50) changes analog wireless signals into digital baseband signals. A complex baseband signal extraction unit(60) extracts a complex baseband signals by using a relative sample delaying difference between a first and a second route signal and generates the first and the second route signal from the digital baseband signal. The first route signal is a down sampling signal by delaying the digital baseband signal. The second rout signal is a down sampling signal without delaying the digital baseband signal.

Abstract: PURPOSE: A dual-band reception apparatus and method thereof are provided to effectively eliminate an aliasing effect generated between two signals by using an analog to digital converter. CONSTITUTION: An ADC(Analog to Digital Converter)(50) changes a dual-band analog radio signal into a dual base band digital signal. A first signal extraction unit(61) generates first and second route signals from the dual base band digital signal. The first signal extraction unit extracts a first base band signal by using a simple delay difference between first and second route signals. The dual base band signal is composed of the first and second base band signal.

Abstract: PURPOSE: A device and method for transmitting a signal are provided to halve a sampling rate using one of a positive frequency signal or a negative frequency signal. CONSTITUTION: A signal distributor(100) distributes base band signals corresponding to a plurality of frequency bands. A frequency converter(200) converts the distributed base band signals into one of a positive frequency signal or a negative frequency signal according to a frequency band. A frequency synthesizer(300) synthesizes the positive frequency signal with the negative frequency signal. The positive frequency signal and the negative frequency signal belong to one preset intermediate frequency band.
