The transmitting RF module includes an integrated impulse generator capable of implementing on-off-keying modulation and pulse position modulation, and an amplifier for amplifying output of the integrated impulse generator. The receiving RF module includes a two stage envelope detector for detecting a received signal and a comparator for converting the detected signal into a rectangular pulse. The signal recovery unit restores the signal from the receiving RF module to a digital signal using the 1-bit digital sampler. The signal processor includes a receiving signal processor for synchronizing the digital signal and decoding the detected signal. The ultra wideband antenna transmits and receives an ultra wideband signal.

摘要： Disclosed herein is an apparatus and method for detecting an impulse signal or impulse sequence to realize wireless real-time location system application in a multipath fading environment. The apparatus includes a band-pass filter, an RF analog unit, and a signal processing base-band unit. The band-pass filter removes unnecessary frequency bands from impulse signals received through a receiving antenna. The RF analog unit detects the envelope of the impulse sequence deprived of the unnecessary frequency bands and based on a multipath, and outputs a digital signal regarding the envelope based on a leading edge of the envelope. The signal processing base-band unit performs low-speed 1-bit sampling and then output data, and, if frame synchronization has been found or a ranging command has been detected, performs high-speed 1-bit sampling and then calculates and outputs the propagation time of the impulse signals.

摘要： A method for detecting a storage voltage, a display apparatus using the storage voltage and a method for driving the display apparatus. The method for detecting the storage voltage includes applying a test voltage to a storage line in a display panel having an active layer disposed between the storage line and a data line while varying the test voltage, the active layer being in an active state or an inactive state according to the test voltage, and detecting the storage voltage corresponding to the test voltage in an inactive state of the active layer. Thus, the display panel is driven by using the detected storage voltage, so that an aperture ratio may be increased and current consumption may be decreased.
