Abstract: PURPOSE: An FFT(Fast Fourier Transform) scrambling and descrambling method is provided to firstly scale an amplitude of an FFT signal in a transmitter, and to scramble a position of a frequency component, in order to modulate an amplitude of the frequency component, thereby reducing residual intelligibility for an original signal. CONSTITUTION: A scrambling process(20) is performed as follows. An analog signal(201) is sampled to a sampling frequency, and is converted into a digital signal(202). An FFT processor binds digitally converted data in certain blocks, performs an N-point FFT process, and converts the data into a frequency region signal(203). A scaling table(220) is multiplied by a frequency component, and an amplitude scaling operation(204) is carried out to generate an amplitude-modulated signal. A position component of the frequency region signal is replaced(205), and an N-point inverse FFT process is performed(206). The signal becomes a real number sequence signal, and is converted into the analog signal(207), then is transmitted(208).

Abstract: A method and an apparatus for detecting a 3D position by using an ultra wide band signal are provided to accurately detect the 3D position of an object by measuring arrival times of reflective pulses from four reception antennas. An antenna portion(40) includes a transmitting antenna, which emits a wireless signal toward an object(5) to be detected, and plural reception antennas, which receive reflected signals from the object. A DSP(Digital Signal Processor,10) generates a trigger signal for locating the object, converts a received signal into a digital value, and outputs the digital signal. A transmitter(20) generates a predetermined transmission pulse according to the trigger signal and outputs the transmission pulse. A receiver(30) amplifies the reflected pulse signal from the reception antennas and outputs the amplified result to the DSP. An information providing unit communicates with the DSP and displays position information of the object on a screen based on location data received from the DSP. A predetermined program for locating the object is loaded on the information providing unit.
