Title: Transmitting and Receiving Method for Digital Transmission of Analog Signal with Complex Frequency and Device for the Method
Inventor: LEE GYU HO
IPC: H04B10/29
Filed: 2001-11-07
Abstract: PURPOSE: A transmitting and receiving method for digital transmission of an analog signal with a complex frequency and an apparatus therefor are provided to reduce the number of bits by allowing a transmitter to convert an analog input signal to a digital signal and transmit it and a receiver to receive the digital signal and convert it to an analog output signal through a D/A converter or a modulator. CONSTITUTION: A down-converter(10) converts an analog input signal with a complex frequency into a low frequency. A demodulator(15) demodulates the low frequency-converted analog input signal in a PSK(Phase Shift Keying) in order to remove or reduce a guard band of the low frequency. The first and second samplers(20,25) sample the demodulated signal with a sampling frequency and convert it into a digital signal. A format interface unit(30) converts the digital signal outputted from the samplers(20,25) into a transmission format to transmit it.
